Sort of. oFono is a full telephony stack, so we expect the basics to be = provided. IMSI availability tells us that the SIM has been initialized = to the point that it is useable. E.g.

Are sim operations supported / working on this modem with libqmi? Regards, -Denis --===============0713062902310444671==--
