I'm not sure on how T-Mobile are blocking, but if it IS my IMEI then you would have to use a SIM from a different network.
If they are blocking your IMEI on their network, then you would have to use a SIM from a different network (as a different network, wouldn't be blocking this IMEI number). Changing it to a different SIM on the same network won't help as your IMEI is for the device itself.
