Help with Activation

Hello!

‘Just switched my i-phone from ATT to TMobile.  Inserted the new sim card given to me by the salesperson at a T Mobile store, and I am receiving an error message saying that the sim card is not recognized by the carrier (T Mobile).  

 

I can’t call T Mobile because the phone is currently disabled. 

 

Help!

    Thank you Gramps 28!  You were correct.   ‘Called AT&T & am back in business.  

     

    Good night!

    Is the iPhone unlocked from AT&T? If not you're going to need to get it unlocked which is why the phone doesn't recognize the Tmobile sim.
