"Unknown SIM State" problem

HI everyone,

I got a “Unknown SIM State” message from command cm sim on a WP7702. Normally the result should be “SIM is absent” or so even if the SIM is not inserted, right?

Thanks a lot.

cm sim info or cm sim?

cm sim. It seems like it’s an issue on wp7702 module. A partner of mine
also have this problem. But at+cpin? gets good result.

use
cm sim info

cm sim is an invalid command
