Does a t-mobile sim card fit in...?

Question

A AT&T phone?

i have a t-moblie sim card that fits in all of the t-moblie phones.

will it work in any at&t phones?

Answer 1

You can use it in any t-mobile phone, wich is the quick answer.

For more information on specific phones check out this website and bookmark it. I did because I refer to it for info on my Blackberry.

If you click on a phone you can scroll down and look at a quickguide, user manual, review, or video demo.  Good luck!

Answer 2

Yeahh , but you need to unlock the AT&T phone or else it wont work . Unlocking it would cost about 30$ or idk at some place . You can also do it yourslef if you know how .  

Answer 3

Yes, since both of them are GSM phones, T-Mobile and AT&T SIM cards will work in each other's phone.
