I've noticed and been trying to debug an issue with the pinephone(pro)'s modem not reading sim cards properly, and I think I know what is happening, but not how to fix it, at all.
Disclaimer: I know jack-shit abt cellular modems and sim cards, so this is just a hypothesis from trial and error of swapping the sim card around.
The Issue:
A sim card that once worked perfectly can no longer make or receive calls in the Pinephone Pro on Mobian.
What I think is Happening:
When you get a nice shiny new pre-paid sim card and put it into your phone, it gets a tiny amount of info written to it, like the network provider, the phone's IMEI, etc.
I swapped the sim to my iphone once for a bit, which worked fine for everything from calls to texting and interwebs.
I than swapped the sim back to the Pinephone Pro, and I believe that the sim now has a new set of information on it that the Pinephone Pro's Modem doesn't fully undertsand.
The Pinephone's Modem now believes that the Mint Mobile sim card is in fact a T-Mobile sim card, and refuses to let me tell it otherwise and set the network to Mint.
It randomly alternates from displaying the network as 'T-Mobile' and 'Cellular' now.
Potential solutions(?):
Force the modem to wipe and re-write the sim card with fresh information every time it is re-inserted into the phone?
Is anyone else experiencing a similar bug?
Have you figured out a solution?
