Step 1: First of all  insert your AT&T SIM into your iPhone 4S, if the SIM is not already into the Slot.

Step 2:  Make a drop-call to 611, after dropping the call, activate the Airplane mode.

Step 3: Now Remove your AT&T SIM and replace with the T-Mobile SIM.

Step 4: Make  sure that the  Wi-Fi on your phone is deactivated completely by disallowing  any automatically connected networks.
