Hi,

I have a problem with some SIM from one provider. The modem stay with SIM_READY and PS : detached.
With others similar SIM from the same provider, it works. The SIM works correctly without PIN code in a smartphone.
Nevertheless, with AT command CPIN, I got CME error.14.

How can I investigate the problem ?

Thanks
