Help & How to

  1. For PIN errors only, try entering the default PIN code in the steps for your phone.
  2. Turn off the device and remove the battery and SIM card.
  3. Check for any damage to your SIM card.
  4. Re-insert the battery and SIM card.
  5. Turn the device back on.
  6. If the above error messages still appear, you will need your PUK code. See Contact Us for options to contact Customer Care to receive this code.
  7. Entering the PUK will require a new PIN code. Power the device off and on again to verify the new PIN code has been accepted (or that the device does not prompt for a PIN or PUK code if you have disabled that security setting).
  8. If the PUK code procedure does not resolve the issue, replace the SIM card. See Replacing SIM Cards.
