Cracking your modem simply means unlocking your modem to use all sim...

You need two softwares to do this:

  • Dc unlocker and Imei Calculator (google to download the both)

  • Dc unlocker will unlock the modem for you automatically. (Dc unlocker is not free, you need to buy unit to unlock)
  • Imei Calculator works when you input invalid sim on your modem and it ask for Password, then you will use Imei Calculator  to find the password by entering the modem Serial (can be found on modem) and click calculate to get the password you will enter to unlock it.
