AT&T 4G LTE Network

AT&T's 4G LTE network allows for quicker access, smoother media streaming, and faster web experiences. LTE technology is capable of delivering mobile broadband speeds up to 10 times faster than 3G. Additionally, LTE technology offers a faster response time due to lower latency--the processing time it takes to move data through a network--vastly speeding download times for web pages as well as improving services such as mobile gaming and two-way video calling.

By the end of 2011, AT&T plans to launch its 4G LTE network in 15 major metropolitan areas, covering at least 70 million Americans. Coverage will continue to expand in the next few years and is planned to be largely complete by the end of 2013.

Packed with fun and productivity (view larger).

And when combined with 4G HSPA+ technology, AT&T is capable of delivering a quicker, more consistent mobile broadband experience than ever before. AT&T has deployed HSPA+ to virtually 100 percent of its mobile broadband network, which enables 4G speeds when combined with enhanced backhaul (via Ethernet or fiber). Backhaul is one of the major pieces of a telecommunications network. Think of it as the limbs connecting AT&T's cell towers with AT&T's backbone network that provides access to the Internet.

Android Gingerbread Operating System

Android Gingerbread

The Samsung Galaxy S II Skyrocket runs the Android 2.3 operating system (dubbed Gingerbread) which features a cleaner, more refined interface with new icons, improved top notification bar, and more intuitive navigation.

Multitasking in Gingerbread allows you the ability to run more than one app at a time. If you're playing a game, you can easily switch to an incoming e-mail and then switch back to the game without losing your place. And like the previous version of Android ("Froyo"), Gingerbread provides support for Adobe Flash Player 10.1 for access to the full Web.

The onscreen keyboard makes it easier to type thanks to additional spacing between the keys and larger font sizes. And the more you use the keyboard, the easier typing will be as the enhanced suggest feature records previous input history to make better suggestions.

The Galaxy S II Skyrocket also brings one-touch access to the popular Google mobile services you use every day. It also provides easy access to both personal and corporate e-mail, calendars, and contacts supported by Exchange Server and Gmail. And through Android Market, you'll get access to thousands of useful applications, widgets, and fun games to download and install on your phone, with many more apps being added every day.

Customer Questions & Answers

Top Customer Reviews

By Robert Felice on January 9, 2012
I've checked out what other reviewers have had to say about this phone, and find myself in agreement with most of them.

The phone is amazing.

Here's what else you need to know:
a) data plan
b) apps
c) user manual

Data Plan: you will need a separate data plan for the phone. My wife has an iPhone 3G, with an unlimited data plan from AT&T. But that phone doesn't use the 4G LTE network. AT&T is slowing building out its 4G LTE network, and it may not be available in your area. You have to buy a plan whether or not you currently have 4G LTE coverage. I was pleasantly surprised to discover that 4G LTE was available in my area, even though the official AT&T coverage map didn't include it.

I bought a 200 megabyte per month plan. It seemed like a lot of bytes. Then I started using my phone. Trulia has a great app that lets you find the houses for sale in whatever neighborhood you find yourself in. You can see the entire listing, just like you can at home on your computer. You can even download pictures (bad idea!) Use an app like this, and the megabytes go down the drain. I went through 30 megabytes in the first 6 days of my billing cycle.

So, unless you sprang for an unlimited data plan, I wouldn't recommend streaming movies, or even your music, off the web. And keep an eye on your usage. You can become a data how a lot faster than you might imagine!

Apps: there's a ton of apps available from the Android store, and Amazon has done a pretty amazing job of providing apps for the phone on their site as well.

So far, so good. The problem is that AT&T had added a number of their own apps, each of which has a low-cost or entirely free alternative. But none of the AT&T apps can be removed.

This is a great phone, I have owned it for 3 days now and i really like it. The build quality is great, even though it is plastic. The phone itself looks beautiful and feels great, the weight is also good it doesn't feel to light or to heavy. The screen is one of the best ive seen on any phone. Everything cant be perfect though.

I am not in a lte market so i cant comment on that aspect. As far as the phone goes you do have to keep a couple of things in mind. The phone has a 4.5 inch screen, although this sounds great it has some obvious draw backs. With the screen being so big one of the draw backs is size. It is not a comfortable phone to carry around and putting it in you're pocket as well as pulling it out can be awkward. I wear slim jeans and this has become an annoyance. When you talk on it you notice the size, it feels like holding a scientific calculator to you're ear.

The second draw back is once again the screen size. This being 4.5 inches it takes up more juice than some of the more standard sizes. I am currently experimenting with ways to reduce battery drain but still end up with a dead phone by the time i go to bed (I am worried about the days i go out and stay up past 11). Another thing that I am concerned about when it comes to battery life is the lte antenna. I am pretty sure lte takes up more battery life than standard hspa or hspa+, and I am a little upset that this phone does not have a switch to turn of the lte antenna. Also unlike most android phones i have used before you do not have the option to switch to 2g networks only, there is probably a work-around for this via the android market but i haven't bothered.

I will not comment on the UI because i find that irrelevant on an android phone.

I've had this phone one week, and am in love with it. The samsung galaxy SII skyrocket the best phone I've ever owned. While AT&T is still installing LTE in our area,(greater Philly suburbs in NJ) the HSPA+ backhaul speeds, are still up to 5 times faster I got 5326(down)&1455(up) with mobile on, and I got speeds close to my Comcast broadband in downtown DC @19K(down)& 4K(up), so I know what the phone is capable of when LTE is finally deployed here.

Okay here is what I really like about this phone. The 8 megapixel camera takes crystal clear pictures with autofocus, and the front facing camera takes very good pictures using the spot button on the touch screen. My only complaint with the camera part is that there is not an exterior button that allows you to shoot pictures , I'm not sure what samsung was thinking there. As far as running programs is concerned there is a whole lot of memory for apps to run (1GB) and this phone blazes through multitasking, with the dual-core 1.5GHz processor. I've had 34 apps running in the background, and could still play the need for speed shift that comes with. The built in 16GB USB memory is nice as the total amount with my 32GB micro SD put it at about 45gb's total.
I'm hopeful a firmware update by Samsung will allow 64GB cards to be compatible when they come out, but the USB out to storage mode is great if you already have a 64-128GB USB stick, like my 128GB corsair GTR , that uses hardly any battery when on the train to DC from Philly, and gives me plenty of storage for movies, music, apps, and games, that have fairly decent storage sizes...

I was able to update to Android 2.3.6 as soon as I got the phone setup.
