We're evaluating RSP with 1oT, and we managed to successfully swap the carrier using RSP with our nRF9160DK, running our standard application.
The nRF9161-DK, running the same application (though with an additional IMU), however, fails to respond to the RSP operations. 1oT responded that "Right now we are not getting any notification back from the card to our eSIM environment (SR - secure routing instance), which usually means that the device doesn't have eSIM support in general."
I tried flashing the Serial LTE Modem application, and enabled USAT events with AT%USATEV=1, but I don't get any events at all, and %USATINFO returns 0,0.
PDP session was open during the test, I was able to ping with AT#XPING="5.189.130.26",45,5000,5,1000 just fine.
Is there additional configuration we need to to with 9161 (as opposed to the 9160), to enable BIP and/or RSP, or do you have other ideas where the problem might be?
