It's unlocked so it can use any Sim from At&t or T-Mobile or any gsm network (Airvoice, H2O, etc)

This is a cdma phone which means it runs on sprint. It does have a sim slot for international use, but is not valid for use on gsm in the US(t-mobile/at&t/etc) A sim card is for connecting to the cell towers, not for storage memory. That is an sdcard.

tmobile and at&t; uses gsm, verizon and sprint are cmda. so it wont work with tmobile ,unless there is a gsm version available from at&t; and tmobile. and its possible it uses both gsm and cmda .make sure to look into it you buy.

According to Wilson LTE works on all carrier with this. I know for a fact the 3G works though because I've had someone at my house with AT&T; and they had perfect 3G signal. I currently have Sprint as well and the LTE works flawlessly with it.

I'm pretty sure that virgin runs off of sprints network. This has been a very fast phone and the only complaint I've had with it is that it freezes every now and then. Other than that... You'll be happy with it.

It uses WiMax. Only Sprint network support it. It would NOT work on AT&T; network.

AT&T is my wireless cell phone provided. Just make sure it's unlock and you won't have a problem at all.

The one I purchased says Sprint on the bottom, and I have been using it successfully. It's backwards though, things like Facebook and some other aps are not compatible

This phone is an unlocked GSM phone, meaning that you will need to insert a SIM card into it to work. Sprint is CDMA (no SIM card) so it will not work with this phone.

No, it is only for gsm. AT&T; & T-Mobile are gsm. Verizon and Sprint are cdma. Sorry, most unlocked phones are gsm.

This version is locked and tied to a Sprint account. I'm not aware of an unlocked version of this particular model.

I don't know about the at&t; vs. sprint issue, but the SIM card could be punched out as either a regular size or micro SIM. I do not have any experience using it with an iPhone, though.
