I've been traveling in Iceland for 4 weeks, and phone has been working fine.
One day, out of the blue, I lost the data connection. But it seemed I could still make phone calls.
I didn't make much of it, but couple of days later, I noticed that I couldn't even make phone calls.
The eSIM was disabled, and my phone said: "No SIM detected. Emergency calls only" (or something to that effect).
I've spent few hours trying to debug this, and look for solutions on this forum, as well as other forums. But no dice.
Even had a Google "specialist" try and help me debug this - of course they barely knew what a custom ROM was, let alone any details about Graphene OS.
As I'm traveling, debugging this is a bit hard.
As far as I know, I didn't do anything to cause this. Either this was due to an automatic update of some software on my phone, or due to some change pushed by the network operator, or Google..? I don't know how they could brick my device tho.
I've tried re-installing "Google Play service" and "Google Services Framework" for example, but no dice. I've tried all sorts of tweaks in settings but to no avail.
Here's where I think the main issue is: I cannot seem to enable the Privileged eSIM management. Upon restart, it's disabled. When I flip it to be enabled, the toggle seems to move, and persists until I reboot the phone. But I can't touch the Google Fi eSIM that's installed. I can't enable it (error: "Can't disable carrier. Something went wrong and your carrier could not be disabled"), and I can't erase it (error: "Can't erase SIM. This SIM can't be erased due to an error. Restart your device and try again.").
I've read something about "Google Services Framework" v33 causing issues similar to the above, and people recommend installing v32 (not sure how best to do that tbh.. Find an APK online and manually install? Feels a bit iffy). But those discussions are from ~1 year ago, and not sure if they are applicable.
Any help would be much appreciated.
