I’m testing GE866 and came to an error while reading the IMSI with at+cimi.
Same startup procedure works with GL865-QUAD and other modules.

I have verified, that "at+cimi" is generally working at a later time in startup, but I expect that it should work after "+CPIN: READY" is returned.

At power on SIM initialization starts reading different SIM files, phonebook, SMS. it is possible that even if the SIM is READY, the IMSI is not immediatelly accesible.
I would suggest to insert a delay of at least 1 second .

I switched to "at+crsm" for reading IMSI.
This is working for both modules.
