The described procedure reset SIM card's fault counter and allow using the card in
MT-101
module.
In older versions of GSM modems without implemented protection procedures the SIM card
may get blocked after 3 failed attempts and the only method of unblocking it is to supply
the right PUK code. Unfortunately this cannot be performed in the MT-101 module.
The PUK code may by inserted only after taking the SIM card out of MT-101 module and
placing it in a standard GSM mobile phone. The phone will demand entering of PUK code at
power-up.
Entering correct PUK-code unblocks the card and resets PIN fault counter making the card
operational.
10.3. Error signaling
Despite the efforts of module designers and users errors in function do occur. It is often
imperative to diagnose and remove the cause of error. Error signaling is a tool for solving
problems.
LED indicators on module's front panel interpret errors:
•
ERR
•
GPRS
•
L1
,
L2
,
L3
of
SGN LEVEL
group
Depending on type, errors are classified as standard or critical. Standard errors are a result
of faulty configuration or reasons independent of the module. Critical errors are usually
connected to physical damage or faults in internal program.
