Hi Denis,

Thanks for your answer, I have used at_util_sim_state_query_new() like
in plugins/zte.c, and it works, CPIN? responds READY. 

But when I launch active-context script, I see that I get an IP address
but I lost it right after. I have try to understand the code but I don't
know why sw_gprs_deactivate_primary() is called, and why after
ofono_netreg_status_notify() is called periodically.

Here is a part of the log I obtain :
