Description

Using osmo-remsim-{server,bankd} version 0.2.2.112-694e
osmo-remsim-client version 0.3.0

If I create a mapping osmo-remsim-client switches to the remote SIM and resets the modem

$ ./contrib/remsim-apitool.py -m 1 0 1 1
$ ./contrib/remsim-apitool.py -a        
/clients: {'clients': [{'peer': 'C1:1', 'state': 'CONNECTED_CLIENT', 'component_id': {'type_': 'remsimClient', 'name': 'client', 'software': 'remsim-client', 'swVersion': '0.3.0'}}]}
/banks: {'banks': [{'peer': 'B1', 'state': 'CONNECTED_BANKD', 'component_id': {'type_': 'remsimBankd', 'name': 'fixme-name', 'software': 'remsim-bankd', 'swVersion': '0.2.2.112-694e'}, 'bankId': 1, 'numberOfSlots': 1}]}
/slotmaps: {'slotmaps': [{'bank': {'bankId': 1, 'slotNr': 0}, 'client': {'clientId': 1, 'slotNr': 1}, 'state': 'ACTIVE'}]}

Events sent by remsim-client: request-card-insert, request-sim-remote and finally request-modem-reset

AT+CIMI now reports the remote IMSI. If I then remove the mapping again I would expect the reverse events to be sent (card-remove, sim-local) followed by request-modem-reset

$ ./contrib/remsim-apitool.py -d 1 0

Even if my expectation when removing the mapping is incorrect - those events are not even in the code:

$ git grep call_script
src/client/main_fsm.c:static int call_script(struct bankd_client *bc, const char *cause)
src/client/main_fsm.c:      call_script(bc, "event-server-connect");
src/client/main_fsm.c:      call_script(bc, "event-bankd-connect");
src/client/main_fsm.c:  call_script(bc, "request-card-insert");
src/client/main_fsm.c:  call_script(bc, "request-sim-remote");
src/client/main_fsm.c:  call_script(bc, "request-modem-reset");
src/client/main_fsm.c:      call_script(bc, "event-config-bankd");
src/client/main_fsm.c:          call_script(bc, "event-modem-status");

There should be a way to switch a modem back to local sim.

I tried to implement this in https://gerrit.osmocom.org/c/osmo-remsim/+/25410 but the patch is untested so far. I currently don't expect to find time to test it, so please give it a try and see if it does what you expect.
