Could you try the following patch against ModemManager? There are two
ways to get the UIM/SIM status, one with the "DMS" service that works
on most devices from 2015 and earlier, and a new way with the "UIM"
service that works on many 2015+ devices. Perhaps the EC21 is new
enough that it requires the UIM service, but ModemManager doesn't
recognize the error code that it's returning. This patch will do that.
You'll still need the libqmi patch I posted earlier too.
