what do i tell at&t when i call to unlock the phone with a t-mobile sim's in it?
You can request for Unlock code...you can specify the brand and model and also give answer to what they ask...they will send the code in mail....But not immediately..They ask to wait for month or some ...If you need Unlock code immediately means get the unlock code from the site Theunlockarena.com/supported-phones/rs13wp7/ and unlock it.
