Hello Sarah. There is a solution for blocked T-Mobile USA iPhones, but we need to make a more deep check on the Block status of that device in order to be 100% sure for the solution. I suggest using our IMEI Unlock Check first and then one of our agents will inform you which service is ideal for your device. If you are 100% sure of your iPhone's status and you do not want a check from us, you can go to the following link and order a T-Mobile USA IMEI Unlock service for your iPhone: https://www.iphoneunlock.zone/iphone-unlocking-solutions/
