RM500Q-GL Issues with 5G SA S-NSSAIs

IoT Modules 5G Module
#1

Hi,

we are trying to connect our rm500q modem to a 5G SA network using different S-NSSAI. It worked well with SST:1 and SD:1 (configured in RAN and Core), but when trying to set another S-NSSAI (e.g. SST 2 or SST1 + another SD) the UE still tries to connect SST:1 and SD:1 although it is not present in the gNB neither in the Core.

We have tried to reboot the modem, but the issue persists. We are using the following FW revision: RM500QGLABR11A06M4G

We tried to use AT+C5GNSSAI to set a different default s-nssai, but it is not being used. This is the output of AT+C5GNSSAIRDP command:
AT+C5GNSSAIRDP=3
+C5GNSSAIRDP: 4,“02.000000” → default, added via AT+C5GNSSAI
+C5GNSSAIRDP: “00103”,4,“01.000000” → the one that is being used and that we cannot delete

Is there any way to modify/delete the configured SNSSAI? AFAIK, it should be selected according to the available SNSSAIs being served by the RAN/Core.

Thank you,
Miguel.
