After last update, my FP5 stopped to detect the SIM card (i have an open support ticket on that matter), but then i thinked: it’s a good occasion to try eSIM.
I have the eSIM, but then my Network & internet settings looks like this:
When going to the reset Option in: settings → system → options for resets, it possible to reset. the mobile network settings or eSim separate. this my help a bit in reducing time to set everything back.
Be aware to do a backup first even for the separate reset options.
if not those resets don’t work you need to do the full Factory reset.
