Telit GL868 and SIM code

Hi!

I was trying to play a little bit with a Telit GL868-Dual module. It is exactly the same (externally) with the GL865-Dual. The data sheets look exactly the same as well.

My code is running fine with the GL865 but not with the GL868. The problem is at the SIM somehow. I have to say that I’ve disable the SIM PIN using an old mobile phone

So, when I am executing the AT+CPIN? at the GL865 the response is READY. This is perfectly OK as I am not having a PIN at the SIM. The module is able to connect at the network carrier and everything is fine!

Now, if I try to run the same command (AT+CPIN?) with the same SIM card but with the GL868 instead… the response is PH-MCL PIN. This is translated as: Module is waiting for Multi Country Lock password to be given!!!

What is that? What I have to do? I was trying the different codes at the SIM (PIN1, PIN2, PUK1, PUK2 etc) but nothing so far. Where can I find this password? How I can connect to the network carrier?
