Will my At&t sim work in T-mobile phone?

[shala]

Just curious. Because my aunt sent me a T-mobile phone today, not knowing i'm with At&t.

Nope. Your A T&T sim card will not work with any T-Mobile cell phone. Your sim card from A T&T will only work with a A T&T cell phone.

However if you have a unlock T-Mobile cell phone (changed in its software) then yes you can use a A T&T sim card. All cell phones are locked to use with their specific carriers only.

yes your phone will work in at&t if your phone is not restricted to any provider. if its locked you need to unlock your phone. unlocking a phone is an easy process now a days. there are many ways to unlock a phone. unlocking can be done through softwares or hardwares or through cables or through codes or by remote unlocking. if you ask me i would suggest codes as the easiest method to unlock a phone. i unlocked my phone through codes through Unlock-Free.com.
