You CANNOT use 2 phones with the same number at the same time. But the Blackberry and IPhone uses different data plans. Every time you change the SIM card, you would need to notify AT&T of the change so that they can change the data plans to match the phone you are using.
Report Abuse. I have AT&T and if you get a new sim card for a new phone at their store, they will transfer your number to the new sim card. I'm assuming you can do the same with T-Mobile. Just try taking both sim cards to a T-Mobile and tell them you want your number transfered to the new sim card.Alissa Â· 7 years ago.Thumbs up. have AT&T and if you get a new sim card for a new phone at their store, they will transfer your number to the new sim card.
