Is this device locked to AT&T? Or will it also work with a T-Mobile SIM card?

Yes. It will not work with another provider unless unlocked. AT&T; has an unlocking policy (www.att.com/deviceunlock).

It's locked to AT&T.; I used to have a 3G iPad with which I was using an AT&T; sim card so I bought this.

By default the phone is locked to AT&T;'s service. If you get the phone unlocked then it is possible to use on T-mobile's service.

I did not try T-mobile. However I used it with AT&T and it works fine. Nevertheless, thir phone is unlocked, theoretically it is supposed to work with any SIM. The only limitation when is the policies and procedures of your carrier. You may need to call them and ask about their user policy on using unlock phone. But, I Bellevue lately most carriers allow the usage of unlock phones.

The one I received was unlocked. I slid in my AT&T; SIMM card and a micro-SD memory device and the phone worked perfectly. Don't know about T-Mobile.

It is a unlocked phone with some AT&T; apps installed. I am sure it works with T-Mobile because I just tried it :-)

Did not try to use the device on T-mobile but suspect it will only work on AT&T as it appears to be tied into their cell service only like the early Ipads were only AT&T or Verizon. There is no indication the device is "Unlocked". However you can get no contract service plans from AT&T and go only month to month if needed.

I think it actually is unlocked. The one I got also has the AT&T; logo on the top, but I'm using T-Mobile as my carrier. So there we go. It should be fine.

This is a GSM phone and is only meant to work on the GSM networks. It will work on T-Mobile and AT&T.; Worked without a hitch on T-Mobile for me. Just get a sim card from them and pop it in and you will be good to go. Hope that helps.

Works with T-mobile for sure. Haven't tried AT&T;, but it should work. I can try it out later if you really want me to.

The phone is unlocked. We use it with an AT&T; sim card. I don't know if it will work with T Mobile.
