8.2. Unblocking of SIM card
Three failed attempts of entering PIN code locks the SIM card and requires entering the
PUK code. The fact that the SIM card locked is indicated by the ERR LED. An attempt to
unlock the module may be performed only when the right PIN code is known.
Necessary procedure:
turn the power supply off,
remove SIM card from the module,
insert SIM to ordinary mobile phone accepting cards from the operator that issued
