Dear support,
I have two M12K21 (Suncomm Outdoor CPE Router) with Quectel inside RM520N-GL (RM520NGLAAR01A06M4G).
I’ve tried to connect to the LTE network by two different operator sim-cards but LIMSRV status both, don’t register to the network.
Both sim-cards identified by router, both are working ok in different indoor router (Huawei for example).
I’ve installed last firmware for M12K21 from SunComm but still NOK.
APN configured manual and in auto mode. Network level is ok. MBN deactivated. Once tried to AT+QPRTPARA=3 - same situation.
Could you please check - what the issue may be in config RM520N-GL?
Thank you in advance!
