Thanks for elaborating Joel! The best place to start would be with the AT Client. This allows you to enter e.g. PIN code (AT+CPIN) to verify the need to for a PIN. Then you can use Facility lock (AT+CLCK) to disable the need for PIN.

We do recommend enabling UICC state notification (AT%XSIM) to receive messages when something is wrong with the SIM or has been removed.

[quote user="JOEBRE"]Unfortunately there is no mean to remove the PIN. Is there any way to enter a PIN (lwm2m client) without using the AT commands ?[/quote]

You can send AT Commands using the Modem library. Have a look at nrf_modem_at.h. You can send AT commands with e.g.

err = nrf_modem_at_printf("AT+CFUN=1");

Kind regards,
Øyvind

Hello, the SIM is a "second SIM" provided in the context of a regular flat data +voice smartphone abo. The second SIM is provided by the operator as a SIM for IOT, wearable, smartwatches,...

Unfortunately there is no mean to remove the PIN. Is there any way to enter a PIN (lwm2m client) without using the AT commands ?

As mentioned, once the PIN has been entered the nRF9161 is connecting properly to the internet ... therefore the SIM is working properly...

Hi Joel,

Did you test with the SIM cards provided with the nRF9161DK?

[quote user=""]I got my second SIM from my cellphone operator and I insert it into the nRF9161_DK board.[/quote]

What kind of SIM is this? Usually a pure data SIM should not need to have PIN code entered for use. Have you tried to ask you operator if this is possible with your SIM?

Kind regards,
Øyvind
