Quick Tip: How to Save Money on Wi-Fi Internet Access on an Airplane

Gogo inflight internetThe price of airline wireless service has been steadily rising, as Gogo recently stopped offering one-time passes on certain flights and instead is charging $10 an hour for Wi-Fi internet access. The good news for air travelers, though, is it definitely pays to prepare ahead.

Yesterday I bought Gogo’s inflight internet access. It cost $14.95 for full day access. I wasn’t thrilled to pay for Wi-Fi, since some airlines offer free Wi-Fi, but those fifteen bucks were a much better deal than what I would have paid if I bought the internet access on the plane: $10 an hour–and my flight is 5 hours long.

I’m typing this using the Gogo service now. It’s about as speedy as the kind you’d get at an Internet cafe or Wi-Fi hotspot–except, well, you’re 30,000 feet in the air. Video streaming, however, such as through Netflix isn’t supported, unfortunately, and YouTube videos also stutter.

The next time you’re getting on a plane and want to get online too, just remember to buy your Gogo access before your flight.

Myth 10

Top 10 Networking Myths

This Avaya CONNECTED Blog
is also available as an MP3 Audio File


Whether your building out a corporate network, or a brand new ESINet for Public Safety, you need to understand networking, and there are some common myths that will leave you with a poor deployment and huge amounts of capitol investment rusting away in the data center while you try to figure out how to save your career.

10)Cisco continues to be the undisputed leader in networking innovation

It is time to stop living in the 90′s, while I won’t spend time to argue that statement, it is time to look at technology and where the market is heading TODAY. I hate to answer a question with questions, but let me ask:

  • Q: Who was first in delivering Resilient Stacking technology?
  • A: AVAYA
  • Q: Who changed the resiliency model from Active/Standby to Active/Active?
  • A: AVAYA
  • Q: Who introduced Split-Plane technology first to market?
  • A: AVAYA
  • Q: Who introduced hardware based 20ms resiliency?
  • A: AVAYA
  • Q: Who has delivered end to end Ethernet Fabric technology AND drove its standardization with IEEE/IETF?
  • A: AVAYA
  • Q: Who has delivered the most scalable 2 Tier Data Center architecture with lower latency?
  • A: AVAYA
  • Q: Who has delivered Layer 2 and Layer 3 Virtual Services Networks with its Ethernet Fabric Technology?
  • A: AVAYA
  • Q: Who has delivered innovative, scalable, resilient and fast registration for Multicast applications?
  • A: AVAYA

Myth 10

Remember, Innovation does NOT EQUATE TO acquisition, so exactly who is the Innovator and who is the follower?

9) Juniper seems to be the logical alternative to Cisco

Due to the unfortunate situation with Nortel Enterprise, many customers and partners were given no choice but to consider alternative vendors. While it’s clear Avaya has heavily invested in Networking, is Juniper still a logical alternative to Cisco? To me at least, it seems their QFABRIC Data Center strategy was a failure, now it’s based on SDN promises?

It’s time for customers to look back at Avaya’s portfolio and the technological maturity it brings from the heritage of Wellfleet, Synoptics, Bay Networks and Nortel. The technology train never stopped, and they are in the lead for Campus and Fabric architecture…time to reconsider Avaya? Yes indeed as Avaya solves REAL IT CHALLENGES TODAY and is in a unique position for many quarters to come…

8) There’s no different between proprietary and standards-based Fabric solutions

While some may think proprietary Fabric Architecture is ok for the Data Center, aren’t we living in an open system architecture world where best of breed technology should be selected?
How will you extend or leverage your Ethernet Fabric if it is proprietary? The world knows better and there happens to be an IEEE and IETF standard out there, known as SPB (Shortest Path Bridging) or if you prefer IEEE 802.1aq or IETF RFC 6329.

Inter-operabiltiy with other vendors has already been proved and the recent flawless performance of the Core at InterNet 2013 in Las Vegas, demonstrates the maturity and stability of this technology. Avaya is leading, time to look at solving your IT challenges once and for all

7) We cannot eliminate Spanning Tree

Do people use a bus to try winning a Formula 1 race?

Do people fly airplanes with one of the two engines on standby?

None of this seems logical, does it?

So why is it customers tolerate building a network infrastructure utilizing a protocol that wasn’t built to deliver resiliency?

The market has clearly endorsed Active/Active as the defacto design model now, and it is time for customers to stop accepting sub-optimal solutions for their network and ensure failures won’t be business impacting. Avaya has 12+ years of maturity implementing Active/Active resiliency, and while other vendors are trying to catch up, Avaya keeps moving the dial further ahead, and maintains its position as the undisputed leader of Active/Active resiliency.

6) MPLS is the solution to all of our problems

Customers that wanted to deploy a multi-tenant and multi-services business solution, had no other choice but to eventually consider MPLS as the solution in order to provide Layer 2 and Layer 3 virtualization.

While that might be powerful and scalable, its level of complexity just made it extremely difficult for IT departments to retain the skill set required to build and maintain it.

What if there was, today, an alternative provide Layer 2 and Layer 3 Virtualization for both unicast and multicast based services? What if MPLS level scalability was achievable without its associated level of complexity?

What if that same solution gave you network behavior flexibility too, so you no longer have to guess how the network is behaving? What if Avaya was once again in the lead, helping you solve these challenges

5) Deploying services must involve weeks of planning and hours of implementation

Today it takes hours, weeks, months of preparation to deploy a new service across your Enterprise. Why? Simply because of the level of complexity associated with extending a service using existing legacy technology such as VLANs’ to extend such services. This translates into nodal configuration, which despite the qualification of your IT staff, requires proper planning and change management control. There is so much business risk associated with such a deployment, nobody will take a chance on doing it without proper testing and configuration validation.

What if you could, today, provision end to end services, but only have to touch the edge of your network?
Basically provision where the service is to be used, and where its being offered and VOILA, you are done. Let the network SERVICE your application needs.

4) Equipment maintenance and upgrade must be business-impacting

“Sorry Folks! Park’s Closed. The moose out front should have told ya’.”

Myth5.jpgIn the past most applications ran in a non-geo redundant or even in a single data center non-resilient deployment model. Now, you can easily deploy every application in an active/active model and woouldn’t it be even more powerful if you take advantage of various hypervisors virtualization solutions?
The combination of Virtualization, applications running in an Active/Active deployment model, as well as having a Data Center architecture that can extend Layer 2 domains where you need to, gives you the utmost flexibility and agility that your IT staff, and more importantly, your applications were looking for, and needed. Well, you don’t have to wait anymore, it’s here….

3) Multicast is becoming mandatory, but it’s complex, unreliable, and doesn’t scale

Everyone has been suffering through Multicast deployments over the last 15 to 20 years. The level of complexity and limited scalability, often gave no choice but to limit its utilization and size of deployment to known logical limits that did not meet the business needs.

What if you could finally scale multicast to new levels, while also addressing the design complexity?

What if you could no longer have to say “NO” when you are requested to deploy a multicast based application because your multicast network scalability is already saturated?

What if you didn’t have to build a separate infrastructure because the one you have is running at maximum capacity and scalability for multicast?

What if you didn’t have to force usage of unicast anymore? Or, what if you didn’t have application failures or business impacting situations due to the lethargic, slow recovery of multicast applications?

Well, there is a solution to your challenges, It’s called Native Multicast over SPB, and it comes to the rescue to deliver a never-before achieved level of scalability, while delivering 500 milliseconds recovery and 100ms or less registration, and delivering all this without the need for PIM!
That is innovation at its best, while still supporting inter-connectivity to PIM domains.

2) Avaya is a Voice company and doesn’t bring anything to Networking

While Avaya continues to be a leader in Unified Communications, Contact Center and Video conferencing, it is important to note its level of competiveness in the Networking area. Not only do they provide cost effective Ethernet connectivity with or without PoE, they also led the way by solving some complex IT challenges such as E911 location reporting, regardless of the mode of connectivity being used (wired and wireless).

While Avaya has a very strong Voice heritage, it also understands the networking requirement and has focused on delivering best in class innovative solutions which customers and partners need to pay special attention too.
Avaya is about innovative Real Time Collaborations, UC, CC, Video and highly reliable and scalable network.

From Data Center edge all the way to your Branch Edge, Avaya can help you solve these challenges TODAY using industry standard protocols and best practices. How many other competitors can say that? Let me help you out with that one. . . .

Pick a number between ZERO and NONE.

1) The future is all about SDN, so you have to wait….

SDN Is gaining momentum in the market, it is like a Tsunami hitting all the IT personnel trying to understand if this is the technology that will finally solve their IT challenges?

While SDN seems to focus on solving relevant IT problems, the question is more “What IT problems is the industry trying to solve, more importantly, what are YOUR business IT challenges”.

What if Avaya was able to solve these problems for you, TODAY with products, solutions, protocols, etc..that exist NOW in an open system architecture that does not require the wait for some new SDN Protocol to be supported by ALL vendors?

What if Avaya endorsed the SDN concept in addressing key IT business challenges?

What if Avaya offered Orchestration and simplification of Applications Provisioning today?

And more importantly….would you be interested in chatting with one of our Experts?

Avaya continues to innovate, but more importantly, Avaya can solve real IT challenges today by changing the way Networks are being built, without waiting for all sorts of promises to be delivered in the next few years. Giving Avaya an opportunity to show you what we can do TODAY, will be a worth while investment, and we promise not to disappoint you.

Google Glass Hackathon Offers Games and Glimpses into Future of Collaboration

From Friday to Sunday in the SOMA district of San Francisco, techie workspace rental firm Citizen Space hosted a Google Glass Hackathon. The event held there turned out to be the largest gathering of Glass Explorers (the name Google gives those who have purchased Glass) to date,. some 30 or so Glass-wearing futurists donated their hardware to the competition. They were joined by developers for the three-day competition, and together the group turned out an impressive 17 unique apps for businesses and consumers alike.

The victors of the three-day hackathon were an ingenious team that made Frogger for Glass. Their winning app incorporated Glass’ accelerometer, which turned your physical movement into the game controls. Hopping moves your frog forward across the road in Frogger Glass. A programming choice that wowed the audience during final presentations and had them downloading the app afterwards. Second place went to Plant Something, an augmented reality app which allows you and other Glass wearers to grow virtual plants at real locations. Third place went to Connected Glass, which was a platform that allowed developers to create peer to peer connectivity with Glass and your other mobile devices so you could control Glass through your smartwatch or smartphone.

IMG_7443.JPG

Even though they didn’t take away a prize, there were other teams that were equally impressive. Standouts included Vitals on Glass, whose team brought to the drawing board one of the more ambitious and marketable apps with a medical hack. The Vitals on Glass app displays vital signs data from surgical patients wearing a ViSi mobile wireless monitor to a surgeon wearing Glass.This fully operational software taps into the fast-growing remote and wireless patient monitoring market, which is expected to double by 2016.

The second standout of the weekend was Powercast, a hack for displaying and controlling PowerPoint presentations using Glass and Google’s new $35 Chromecast device. Darshan Shankar presented his final version of Powercast, and the results were stunning: Shankar showed how he could view a Powerpoint on his Glass or on an external monitor or screen with a Chromecast inserted into it, as well as move around the slides by swiping his Glass or wirelessly-connected smartphone. The problem with this? Chromecast’s SDK is still in Beta and developers aren’t supposed to be hacking it just yet. Shankar’s chances of winning may have been hindered because he created a hack that he can’t go out and market yet. Still, he explained it was only a matter of time before the ban was lifted and he could spread Powercast to the Glass masses.

And that seemed to be a key deciding factor at the hackathon. The winning hacks were not only fully operational and utilized more parts of Glass than just the display, but were also immediately accessible. Glass Frogger already has a website up and running for people to download the game on Glass and other mobile devices. So while the future was on display, the future that was immediately accessible was rewarded.

While Frogger stole the show, Vitals and Powercast do show immense promise in bringing Glass to industries as a tool when it becomes available next year. While Google wants Glass to revolutionize consumer tech, it’s hard to imagine non-early adopters to latch onto such futurism. Reports of it being goofy looking and an intrusion of privacy make it a hard sell. However industries are jumping onto the Glass developer bandwagon.

Glass wouldn’t be the first consumer marketing tech to find more love in business. Microsoft’s Kinect had a lukewarm reception among gamers, but has become popular outside of that world: whether it’s to turn it into a 3d scanner, to train a robot to be a jedi, or improve a nuclear power plant’s safety. In fact the healthcare field was one of the first to jump onto the Kinect bandwagon, something that we’re seeing with Glass. Vitals on Glass isn’t the only team who thinks Glass could have a future saving lives, and certainly won’t be the last. And Powercast is tapping into a predicted trend of hands-free tech in the workplace. Even if the general public balks at Glass, hackathons and industries will bring it to the forefront of the future as a cutting edge tool. Which means someday soon you may have the pleasure of downloading the One-X app for Glass.

Public Safety Networks Report

E911 Location Failures – What’s up?

This Avaya CONNECTED Blog
is also available as an MP3 Audio File


The popular belief is:

[When you dial 911, your call ends up in a massive modern control room like environment that could be easily mistaken for NASA with all the latest bells and whistles that tells the 911 call taker exactly who you are, what you're calling about, and your precise location]

Right?

Well, that might be the way it works on TV and in the movies, but the fact of the matter is the majority of 911 centers or PSAPs in the United States (about 80% of them in fact according to NENA) are only 2 to 4 answering positions. While the large “mega-centers” do exist in cities like New York, Chicago, and Los Angeles, they are certainly the smallest percentage.

Likewise there’s a mass misperception by the general public on the technology that a 911 call taker has at their fingertips. To those of my readers that are in the industry, it’s no great secret that the only “information” that is received on a 911 call is a telephone number, and the local equipment uses that phone number to query the telephone company database for the subscriber information resulting in the address. While that’s technology that is useful for residential fixed endpoints such as land lines where a telephone number equals a physical street address, that method of location discovery is completely useless for a device that is mobile by nature such as a cellular telephone.

Since cellular phones can be used anywhere in the country, when they make a 911 emergency call the number that is displayed initially at the 911 center, is a special number that is actually representative of the tower that is handling the call. This is known as “Phase I” location reporting. This number is called a pANI (pseudo Automatic Number Identification). While this provides the 911 call taker with a very general area that the call is coming from, it is initially used for determining what 911 center needs to get the call. All cellular calls, that’s right ALL OF THEM, initially arrive at the 911 center with Phase I location information.

While the call taker is working the call, about 8 to 15 seconds later, the 911 equipment makes a second query on the pANI number received, and by this time the cellular network should have been able to determine a more precise location of the caller, and returns that information along with subscriber data in what is called Phase II location information. Depending on the technology used to locate the device, the information is also assigned a reliability or accuracy score.

When the planets are all in alignment, and the 911 gods are shining down upon the network, this can produce fairly accurate location information, and in fact the FCC mandates that carriers provide this level of location accuracy on a certain percentage of calls. Now that you have the background information, here’s the earth shattering news that was published earlier this week in a letter to Acting FCC Chairwoman Mignon Clyburn by CalNENA president Danita L. Crombach, ENP.

The letter cites several alarming factors that came to light after a study of real-time data over a two-year period by public safety analytics company Public Safety Network. The data focused on the amount of cellular phone calls that had received Phase II data by the completion of the call.

The report focused on four areas within the state, San Francisco, San Jose, Bakersfield and Ventura County and noted that statewide, 45% of wireless 911 calls lacked Phase II data, with some areas such as Ventura County lacking that critical location information on more than 50% of the calls. Was it a particular carrier worse than the others? Not really, although some were better and some were worse the problem was consistent across all five major carriers (AT&T, Metro PCS, Sprint, T-Mobile and Verizon) and the report shows that even under the best scenario accuracy never surpassed 64% in December 2012.

Public Safety Networks Report

There’s quite a bit of speculation why these numbers indicate the problem is getting worse. While no specific hard analytical data was collected to define the root cause of the problem, it’s generally accepted among experts in the industry that to specific phenomena contribute to the problem. The first is the fact that cellular device saturation in the United States is estimated to be at 103%, meaning a device for every person in the country, plus a little. That first factoid directly leads to the second, where people are using their devices more and more inside of buildings and what the report calls “urban canyons”.

iStock_000002375961Small.jpgThe urban canyon actually has two negative effects on cellular location discovery. The first is the fact that GPS signals typically need to be what’s called “line of sight” and therefore do not penetrate steel and concrete rendering them ineffective indoors. The second problem affects the backup location discovery mechanism typically used known as TDOA (Time Delay on Arrival). In layman’s terms, this is the time it took for the signal to travel between the transmitter (the cell phone) and the receiver (the cell tower). Given that radio waves travel at the speed of light, the distance between the two becomes a simple mathematical calculation. Using this information from two or more cellular towers, and old-fashioned radio triangulation can be used to pinpoint a transmitter’s location with surprising accuracy. Unfortunately cellular radio waves “bounce” off of buildings and do not travel in a direct line. These signal reflections, if severe enough, can actually increase the distance traveled skewing the calculation.

Bottom line, more people are carrying cell phones, therefore more people are making 911 calls from their cell phones, and people are within buildings during the work day. Add all of that together, and you come up with a decrease in accuracy statistic. Not because the problem got worse, but because more people are using the problematic method.

Now while this specific report covers California, one would imagine that this same phenomenon exists in every major metropolitan city across the US. So while communication habits have drastically changed with the multitude of smart devices now available at our fingertips, if we’re going to continue to enjoy an accurate level of public safety communications, the Federal Communications Commission is going to need to step in, and as the report states, “issue all necessary orders” to correct this problem.

So just bring this into full circle, if you have an enterprise PBX, and you feel that your cellular phone is a suitable replacement to addressing E911 within the enterprise, based on the information in this report you may want to think that over again.

How We Built an Advanced Live and Streaming Event Solution on a Shoestring Budget

Every company needs it, and every marketer dreads it – the All Hands Call. Though it seems simple enough to bring everyone together to share corporate results, messaging and updates, it can get pretty complicated behind the scenes to mix a room full of people in a live event with a large team dialed into a collaboration bridge (video / web and voice) while ensuring that everyone has a quality experience.
When we built our room, I had the same needs that most of you probably have too. I needed a solution that was:

  • Easy to use and train people on
  • Easily accessible to internal and external participants
  • A high quality experience
  • Easy to build out quickly and flexible to add to over time
  • Extremely cost effective

With that simple task in mind, I went about pulling together a solution to hold effective meetings that would include a quality online and live experience. Luckily at Avaya, we have several technology solutions that allow us to create great online conferencing experiences. Just for fun, we have rotated through several of the various solutions we have available, and I’m happy to say we have had success with all three of our major conferencing applications using this setup, including Avaya Aura Conferencing, Avaya Scopia and Avaya Live Engage. (Each has unique strengths depending on what you want to accomplish in your meeting – but more about that in a future blog post!).
When holding a meeting, there are 4 things you need to think about at the same time:

  1. Audio from the person presenting, which needs to be crisp and clear
  2. Presenting content, usually in the form of slides
  3. Video of the person presenting, which needs to accommodate for their movement and feel natural
  4. Someone to moderating the meeting, ensure that the audio, video, presentation are broadcasting properly, and that participants are well managed, muted, unmuted, etc.

As a musician, the audio piece came to me the most naturally, so I attacked that first. Here is a high level overview of the install we chose. (Don’t let this diagram scare you! It’s actually quite simple).

audio_setup.png

First we had speakers; a projector and a screen mounted in the room and placed a mixer and amplifier in a small AV area to get sound to the room.

To capture sound in the room, my solution was to use wireless lapel and handheld microphones in the presentation room, and put all of the receivers in a smaller AV area. The wireless receivers connect to an 8 channel mixer. The secret ingredient in the mixer is having an Aux channel. The Auxiliary channel is used to control what is sent out to the audio bridge, while the main faders are saved to control what is sent out in the live room. This means that I can put music out from an iPOD on the room, but not broadcast it onto the audio bridge or vice versa. (See below).

mixer_channels.png

The magic that makes this all work is a very cool Avaya Conference phone called the B179. It has a breakout box option which allows you to send high-quality audio feeds directly through a phone line. I use the Auxiliary send from the mixer to feed audio to the conference phone.

Here is the phone and breakout box – the black cable sends the audio in from the mixer, the white cable sends audio out from the bridge to the mixer. (IMPORTANT – for the mixer channel that carries the audio out from the phone, you MUST keep the auxiliary send knob for that channel at zero. Otherwise, you will end up feeding audio from the bridge back into the bridge. Nobody will like what that sounds like!!!)

b179.jpg

And here it is attached to the mixer.

b179_mixer.jpg

Now that we have audio to and from the phone, everyone on the bridge can hear any audio we send them from the mixer, and anyone in the room can hear the microphones in the room and everyone on the bridge. Perfect!

Regardless of whether you choose Avaya Aura Conferencing or Avaya Scopia to handle your meeting, you are going to dial in your audio to the meeting using the B179 conference phone. Now all of the audio for the meeting is going to come in via the audio bridge. (Instead of using a conference phone, you could use a PC to capture sound from the mixer and send it to the conference. I find that the phone setup provides me with excellent audio quality, allows me to put the conference in lecture mode if I have noisy participants and offers a lot of flexibility without supervision, your preference may vary).

With audio out of the way, it’s time to tackle our last 3 elements:

  • Presenting content, usually in the form of slides
  • Video of the person presenting, which needs to accommodate for their movement and feel natural
  • Someone to moderating the meeting, ensure that the audio, video, presentation are broadcasting properly, and that participants are well managed, muted, unmuted, etc.

It is very difficult (though not impossible) for one person to effectively handle all of these things while presenting to a large live audience. To make it easier, I split these tasks across 2 laptops – one that presents content, and one that is manned by the moderator. The result is something that looks like this:

conference_setup.png

PC #1 remains at the front of the room and is connected to the room projector. It is also logged into the conferencing application we are using, and is presenting the slides via the web to remote collaborators as well. The PC is under the control of the presenter, who advances slides using a wireless presenter.

PC#2 is 10-15 feet back from the front of the room and is logged into the conferencing application. This PC is where a lot of the magic happens, and someone needs to pay attention here during the whole meeting. A high definition webcam picks up and shares video of the presenter. The moderator mutes everyone else’s video, so that the room video is the only thing showing in the video window. If the bridge is kept open, the moderator mutes noisy participants here. The moderator also manages the chat window – providing feedback from those on the bridge to presenters in the room.

One thing to keep in mind with this setup – in order to be heard outside of the room, you must be speaking into a microphone! This setup feels so natural to people in the room, they often feel like they can talk to others on the audio conference as if they are there in the room. As the moderator, it is your job to make sure that you pass along the microphone before questions are posed!

Another benefit to this setup – Avaya Aura Conferencing and Avaya Scopia allow me to record the sessions for later playback / editing. This has made our presentation room a great resource for recording training sessions. Downloading the video also allows me to strip out the audio from the conference, and make it available to others as webcasts. (The B179 phone also accepts SD Cards, and will record the session for you so that you can do this without manipulating video files, which is super cool!).

So there you have it – an AV setup that can easily transfer Avaya Aura Conferencing or Avaya Scopia into a powerful multi-site presentation / training and broadcast system. The entire budget for this project will run you around $4,500, depending on the quality and quantity of the gear that you require, and what you already have installed in your boardroom or training room.

If you already have an Avaya Conferencing solution, you’re 90% of the way to empowering your organization more effectively – and forever eliminating your fear of the dreaded All Hands Call.

Good luck!

This Is What Hackers See When You Use a Public Wi-Fi Hotspot

Like many other tech writers concerned about security, I’ve noted before the dangers of connecting to an unsecured wireless network. Using an open Wi-Fi network without precautions is, simply, not safe. To drive the point home, here’s everything an eavesdropper can glean from your computer usage at a coffeeshop or other Wi-Fi hotspot.

PCWorld’s Eric Geier did some innocent snooping at a local coffeeshop to find out what he could see. It turns out it’s relatively easy for anyone to sniff sensitive information such as emails, passwords, instant messages, and website logins if the target (the person using the public wireless hotspot) doesn’t protect that data. Geier could capture FTP login credentials, hijack popular web accounts (such as Gmail, LinkedIn, Yahoo, and Facebook), and more.

Pretty scary. If you’re heading to the local library, coffeeshop, airport, or hotel for internet access, make sure you follow these Wi-Fi hotspot security precautions to stay safe before you get connected.

Take Your Smartphone with You When You Travel to Another Country

You’re planning on crossing international borders, but don’t want to leave your smartphone behind. After all, it’s got your contacts, apps, and other important data on it. The problem is, wireless cellular networks aren’t the same for every country.

It’s particularly divided in the US, where Verizon and Sprint use CDMA technology and T-Mobile and AT&T use GSM–the network technology used internationally in over 220 countries. If you have a CDMA-only phone, you’ll have to rent a phone or mobile broadband device when you travel overseas. GSM phone owners can more simply rent a SIM card (see more caveats here, though).

If you’re traveling with an iPhone or Android phone from another country to the US, here are your options on T-Mobile and AT&T for getting internet access and calling features on your own phone.
