## Customer Reviews

### ⭐⭐⭐⭐⭐ Best USB GSM Modem
*by T***K on January 26, 2011*

This modem is much better than the one I used to use. I switched from a T Mobile usb modem to this brand new Sierra Wireless one. It comes unlocked, even though it says it is not in the product description. (At lease mine was unlocked). I use it when I travel abroad, and it works perfectly. The only downside I have noticed is that it eats battery life. I have a netbook that is supposed to get around 8-10 hours of battery life, which it does. However, when this is plugged into it, I only get around 4-5 hours of battery life. Otherwise, I think it is great. It comes with the ATT Communication manager on the device itself, and auto-installs when you plug it in. It also has a Micro SD Card reader, I do not use it, but some people find it helpful. It saves a USB port so you can use it as a USB Memory stick and a USB Modem at the same time. As of now, I have not had any problems with at all. I do not expect to have any.

### ⭐⭐⭐⭐⭐ Warning:  Requires Special AT&T Plan
*by S***L on April 20, 2011*

First off the Modem works well (or as well as the signal will allow). Installation was fairly easy - had to download the software from AT&T instead of reconizing the device and self installation.My only problem is with AT&T. I had a regular data plan for my smart phone and hoped that I could use this with my sim while I was on vacation. Nope. It worked but AT&T sends you a bunch of messages saying that you need a different plan (extra $45 / month), and then changed my plan to accomidate the modem and not my phone. Once I call AT&T they restored my orginal plan.That said, if you want celular modem coverage, you need the modem and another Data plan.

### ⭐ Don't Buy It
*by A***R on September 30, 2011*

I bought this thing thinking it would be good to have 3G on my tablet computer. It never worked correctly and when I uninstalled the software, my internet stopped working completely. I took it to a local AT&T store & the technician worked on it for more than an hour and could not get my internet reconnected again without reinstalling the AT&T Commincations Manager software that came with this aircard. He said it was a common problem and there was no fix. Needless to say, unless you want to permanently damage your internet connection, don't install this device on your computer. I bought the AT&T Mobile Hotspot Elevate 4G instead and it works perfectly...comes with a 2 year contract but it is quick and will support up to 5 PCs at the same time...a much better buy than this aircard.
