  1. Get in touch with T-Mobile Customer Care to request the PUK code

  2. Enter the PUK code on your device then press "OK"

  3. Type in the new PIN code and select "OK"

Related Errors (cases in which you need a PUK Code):




  • "PIN code blocked. Enter PUK code"

  • "Enter PUK code"

  • "SIM card locked. Emergency calls only. Please contact Customer Care"
