Input:
Question: Can I use this device with other company different than att? Is it locked only in LTE but unlocked in GSM/3G?
Document: well,Permit me to use the Apple example>>when an iPad is marketed as being the AT&T; version,its assumed that any GSM sim in Europe and otherwise will work on it.Meaning that the device is unlocked..in the TF300TL's case it was not.It is specifically for AT&T; use and is locked to their SIM card and network.
We are using these for work and these device are durable. The performance has been great. The only problem I had was getting VPN to connect to the corporate network with the native VPN settings. I ended up having to use VPNCilla.
Definantly recomend it to anyone that prefers a mouse.Update 1/19/13- I have now created a little docking aerea on my desk where i have a USB hub plugged into the dock. Android does support multiple devices being plugged into one usb port. But there is a small catch, it doesnt seem to want to recognize multiple storage devices. It will accept a mouse and a storage device, but not 2 different storage devices. Only slightly annoying.
The best think what I love in this tab - very easy to use! Especially good for people who is not good in computers.Would be better if Android had a little more functions, e.g. first unpleasure thing was no possibility to create folders (as I did easly on Samsung version of Android). But probably this is a question to ASUS company.In general I am satisfied. Thanks!
So far seems like a good purchase. Did it for the 3G vs the TF700 currently out which doesn't offer 3G. Simple to get a hang of. Also for those who avoid it to to lack of flash player support, you can find a way around it like I did.
Not what is advertised, but not too bad at all.And I completely forgot to mention ... This little guy has 4G LTE .... yes baby !!!
I have been using tablets since the Nokia N800, and this is by far the best and most usable I have owned. The screen is crisp and sharp. It is fast and responsive. I have the keyboard, and love the versatility. The LTE is almost as fast as most wifi hotspots, and keeps me connected anywhere I end up.
I loved this tablet. The screen is beautiful. It is fast enough for me.However, first, the one that I received was not LTE but wifi only so check this at once. I had to send mine back and reorder another which was a big hassle. I had already set it up  for my tastes (two or three hours work).Second, the updates from Google Android came slowly but did come (to 4.2.1 Jelly Bean).
This tab is no different from the regular tf300t(aside from the obvious lte part). I am writing the review from the tab with no dock. The asus keyboard is slow and cumbersome so i recomend turning the google keyboard to default. The only other thing i recomend is swype beta, works great. I actually bought this tablet from Best Buy expecting a regular 16Gb tf300t, no lte for $280 on sale. When i recived it, even the Best Buy guys didnt know this version existed.
I use this for entertainment and not business so works great for me. I have a 2 tb external hard drive and it reads the media with no hiccups!
Answer: I had no limitation on provider. I could any that I wanted..
