After receiving my Thingy:91, all was working as expected until I found that the included 10MB of data on the iBasis SIM had been used up and the device refused to connect or do anything. I purchased some additional data via the link from nRF Connect for Cloud but this still didn't solve the issue as the device was not flashing at all when switched on.
I then installed nRF Connect v3.5.0 & upgraded the Modem FW and reflashed the Asset Tracker application. When I switch on the device now, as long as the SIM card is not in place, it flashes Cyan and I can see it booting etc but as soon as I do this with the SIM inserted, it starts to flash red after a few seconds.

This is what I'm seeing in the nRF Connect app when the SIM is in place.
Does anyone have any thoughts on what I need to do to get this back working again?
