USIM compatible with RM500Q-GL


we are testing the 5G chipset RM500Q-GL with the sysmocom sim cards sysmoISIM-SJA2 but we are getting errors and not able to register to the network although 5G network is detected with AT+COPS command,
please note that RM500Q-GL chipset works fine with sysmoUSIM-SJS1,
Could you kindly elaborate? Are you aware of the issue?

Thanks in advance,

Hello Sir,
Thanks for using RM500Q module.
Could you check the ATI/AT+CPIN?/AT+CGATT?/AT+QENG=“SERVINGCELL” commands?
what is the difference between SJS1 and SJA2.
By the way, could you answer following questions, thanks!
