So, I installed GrapheneOS on my Pixel 6 a few days ago.
Since that point, there has been intermittent issues with the data. Sometimes the phone shows "5G" and data/internet works fine. Other times, I get a "LTE" with the "!" no data indicator showing - and, thus, no data/internet connection.
The only thing I can think of that the problem is: When I set the phone up, the Mint Mobile APN settings were not what Mint recommends on their website (for Android phones). I tried to add a new APN, with Mint's configuration specs, but GrapheneOS would not SAVE the APN... the only option I have is about 7 different "fast.t-mobile.com" APN's to choose from. No Mint APN option!
Does anybody have any advice on how to get the data working correctly with Mint Mobile?
