Page 76 Note! The unit will only try a PIN code (or PUK code) once. This is to avoid accidentally locking the SIM-card if multiple connections are attempted. Therefore, it is safe (but useless) to retry a connection with an incorrect PIN code that has already been tested. Copyright © Sigicom AB 2021...
