Yes. I actually ended up provisioning mine for T-Mobile. You should have no trouble using them as your carrier, as it does come fully unlocked.

its an att simm card. if not activated you must call att to activate. att does work on a t mobile phone. if card is yours and already activated from att it should work rivht away in a tmobile phone. good luck.

The phone is sold exclusively for AT&T;, although I liked the phone and purchased an un-locked phone to use it as a T-Mobile customer. Find the plan you like whether it's Tmobile or at&t; and purchase an unlocked phone. You will be happy with both your plan and your phone.

I bought it cause I use only prepaid. I believe T-Mobile has many plans and you can use any of there phones.I would call up T-Mobile. My daughter uses this phone and the only complaint she has is that it freezes up sometimes. But don't all phone do that at one time or another?

Yes you can use AT&T simcard, this phone is unlocked so it works with any mobile operator. I use T-Mobile

IIRC, yes, you can. You may not be able to access the higher speed data LTE or HSPA (4G/3G) services since T-Mobile and AT&T; use different frequencies.

I would ask the seller. I've bought att and t-moble phones only when I was with those carriers.

Yes, you can use your SIM card, and that's exactly why I bought it. I did not want to enter into another agreement with AT&T;, and additionally, I like a flip phone... and these are a dying breed. If you're looking to put your SIM card in... by all means, purchase the phone. Make sure your contacts are Saved to your SIM card from your old phone, to avoid having to re-enter. Good luck!

Just to understand correctly... are you asking to buy my phone or are you asking if TMobile will let you buy it and a Sim card and allow it to work for you? Sorry for any confusion, just want to make sure I understand.

No it takes a regular SIM card which you can still get if you go to any T-Mobile store.

No, because you need a chip from t-mobile, and the phone doesn't have the port for the chip. As least I am pretty sure it doesn't. I don't really use the phone anymore since I have a windows 8 phone. I will check, but I am 99.9% sure it doesn't have the port for it.

Yes.. I used to have one and as I recall there was SIM card slot and since T-Mobile and ATT are both GSM Networks that require a SIM it will work at either service. Anything with a SIM will need as GSM Network such as TMobile, ATT StraightTalk etc.....

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.

My Ipad came with a AT&T; chip, and I dont see it would not work with other service providers' data plans. Besides, my purchase was for overseas use, and it works just fine here.

If it a unlocked smartphone and take t mobile or at&t; service sim card answer is yes check eBay type Nokia 521 unlocked smartphone check phone info should tell you you can use t mobile sim card because t mobile use all different smart phones with their sim card.

I did not buy the phone from t-mobile and it works fine. You will need a t-mobile simm card however which you can purchase from t-mobile if you do not already have one.
