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.

I've owned this since 2009 and it has always gotten a pretty good signal in the remote oilfields where I work even without an external antenna. The fact that you can plug in a high gain external antenna makes it one of the better modems for rural users.

AT&T software is adequate for most users. Easy setup and "Presto", internet.

Device is heavy and is very well constructed. The jointed USB hinge is very useful in many situations. I use the Sierra Wireless branded wireless software and is better than the at&t branded software suite. If you are using this with a mobile phone SIM (not a data-only SIM) the APN's are widely available on the web and do work. I am using this with my iPhone SIM, personally. I get pretty good signal strengths and tested with DSL reports getting very good speeds (greater than tethering to an iPhone,) rating in the megabytes per second. I am very satisfied with this product and have already recommended it to several colleagues.

One thing to note; The vendor I purchased this from advertised it as new but it arrived in non-manufacturer packaging (some generic cell phone package) and was without the USB extension and display mounting clip that would have otherwise been provided with a new and manufacturer packaged item.

I purchased this item for occasional use. I bought it third party because I didn't want to lock into a plan. I have 2 cell phones (1 personal, and 1 business). When I need to get on the web from a remote location, I set call forwarding on my personal cell to the work cell, then pull the Sim out, and install it into this modem. We were recently on vacation, and the WiFi in the hotel was very bad. This device saved the day. I'll probably only use it less than 10 times per year, but for 40 bucks and my data plan work-around, it's worth it.

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.

Since I cannot tether with the iphone - this device allows me to purchase time (1 day) (1 weekend) (1 week) (1 month) when travelling and you need access for your laptop. awesome when you need it for occasional travel (domestic) (weekend at the cabin). and the big plus is no contract or month to month payment.

I ordered this device and came right away, in a few days. Plugged it in and linked up to AT&T's communication manager and has some trouble linking up. Called the Cust Assist and worked on getting new driver software installed via my Wi-Fi and still had a problem. So I downloaded the AirCard Watcher software and it sync'd right up to the software no problem. Then I tried AT&T's manager again and wha-la it now works. I like AT&T's more due to the info on usage and days that laps, and also the WiFi connection link. This Lightning is great and a much faster 3G signal (7.2mbps) than the older one (3.6) I bought 3 years ago. I also like the slim design and the swivel usb connector for the hard to hook up situations, plus there is no battery to worry about on this one. I'm satisfied!

I bought this device for a backup in case my older Sierra 305 dies, tried to see if this newer device works, come to find out you can not just put in an AT&T active SIM card and be connected as stated, all AT&T devices need to be activated with the device IME number, and since my older Sierra 305 data connect modem is still working I am not sure if this one works or not, will just have to wait and hope for the best, do not want to go round and round with AT&T switching out IME numbers in case this one does not work, the seller(s) really need to make it clear that AT&T need to call with the new IME number to make there device work....

UPDATE..... after writing this review and contacting the selling of the issue, they were awesome and responded with wanting to give me a full refund on this device, I am refusing the refund, that was not my intent, I am still going to keep it trusting it to work in the future when my old modem dies, I do deeply appreciate the offer, and would seriously buy again from this selling in the future..... HAPPY HOLIDAYS!!!!
