I put my public mobile sim, in my galaxy S7 and it asked for the sim PIN. I typed in the 4 digit number which I made when I was setting up my account. It did not take the number and I am surprised coz I wrote down my PIN so there is no way I put in the wrong numbers.
After the third time of denying my sim network PIN, it is now asking for sim network PUK and I don't know what that is.
Please help.
SIM Network Unlock PIN is a code used to unlock the phone for use with other carriers.
Your phone is asking for the SIM Network Unlock PUK becuase of the code guessing. This code is needed to reset the ability to use the SIM Network Unlock PIN.
Before anyone makes the suggestion, this isn't anything that the moderators can help you with. If the phone is asking for these codes with the Public Mobile sim card inserted, the phone is locked to some other carrier.
