Thanks Andrew.

I will surely follow your remarks.

Just some queries ::

a)
Is unlocking the SIM via PUK/PIN a one-time process?

b)
Also, I believe (please correct me if I am wrong), that different SIM cards would have different PUK/PINs.
So, each SIM card needs to be unlocked on an individual basis?

Thanks and Regards,
Ajay

Hi Ajay,
Ahh no difference, so it just looks like your SIM has PIN code request
set. If you know the PIN you can unlock from the terminal like
AT+CPIN="0000" if the PIN is 0000 etc
You only get 3 tries at PIN, so if you don't know it then you should call the
operator and get the PUK code first. This will unlock the SIM in the event that
attempting to unlock it blocks the SIM card.

Hope it helps,

Andrew
