How to check the sim lock status of HTC phone

For GSM phone (AT&T, T-Mobile etc):

  • Insert a sim card from a different carrier
  • Turn on the HTC phone. If the phone is locked, it will prompt you with "Network is locked, please input unlock code"

For CDMA phone (Verizon, Sprint etc):

  • Turn off the phone
  • Hold down the Volume Down + Power keys. It will show the flash screen
  • It should say "SPL-0.57 Cmonex" if the phone is unlocked
