Why isn't my unlock screen coming up on screen for unlock code?

Unlock screen not coming up on screen for unlock code

I have put in 3 different unrecognized sim in my Huawei raven lte h892l to put in the unlock codes to unlock. It boots right up to home screen and says invalid card in left corner. How do I unlock with codes I purchased without that screen not coming up after powered on? Please help!

It sounds like a SIM unlock has been set -- do you remember the PW you set?
