If I deactivate my phone, will my sim card be deactivated?
If you're suspending the line or canceling the line or porting the number, all will render the SIM card inactive.
The Sim is what Makes the phone Function, to the Network you pull out the Sim you can install it into another Device if its compatible Like moving the Sim from a Samsung to a HTC if your doing away with the Line completely the Sim most likely will no longer function..
