(e)Sim switch in RUTM30

Networking Solutions
1

Hello,

we have a RUTM30 (RUTM_R_00.07.17.5) at an autonomous/only remote controlled installation. We installed a physical global IoT Sim (our backup, minimal data volume but works almost everywhere) and tested with prepaid travel eSims the available network providers.

We activated Sim switch with “No Network”, “Network denied” and “Data connection fail” at Default Sim (eSim)
The other eSims and the physical Sim have also “Switch to next Sim after Timeout” (20 min) active.

First problem:
Unfortunately Sim switch did not switch back to the Default Sim from the last one in the list.

Second problem:
Due to high data volume needed, our customer (also not on site) provided us an eSim with unlimited data plan. We installed the eSim but there is an SMS activation needed to use mobile data. Is there a possibility to automatically send this SMS when I’m connected to the corresponding SIM card? There is no one on site and with this eSim I currently have no remote access because data has to be activated with SMS.

Feature Request regarding multiple eSims:
In RMS Metrics –> Mobile data information we only see the total data usage of all eSIMs. Is it possible to refine this so that the data usage can be attributed to individual eSIMs?
Also in Dynamic Information it would be fine to see not only Sim1, Sim2 and eSim but also which eSim was active.

kind regards
Stefan.

Unfortunately Sim switch did not switch back to the Default Sim from the last one in the list.

Maybe this may happen when in “Time Synchronization” “Operator station synchronization” is active and different operators use different times (in my case UTC and MET)? If found several time jumps (+/- 60 min) in the log files.
I disabled this feature and will get my time only from NTP servers.

Greetings,

Did disabling that feature help resolve your SIM switch issues, or do you still need further assistance?

Regarding eSIM activation, you can send an API POST request via SMS to the router so it sends an activation message.
Here’s an example of how the SMS command should look (note that the modem ID may vary):

device_password api post /messages/actions/send {"data": {"number":"+3706000000","message":"activation message","modem": "1-1"}}

At the moment, it’s not possible to view mobile data usage per eSIM profile in RMS.

Best Regards,
Justinas
