JohnnyBravo Am I right to assume that, e.g., Vanadium works ok over Wi-Fi? Is it easy to visit an area that is "real Verizon", or at least served by a different carrier? Is it easy for you to try a different SIM card (ideally from a different carrier, but even from a non-iOS device on your carrier could be interesting)?

If you pull up the status screen (Pretend to "call" *#*#4636#*#*, select "Phone information"), do you see anything interesting? What is your preferred network type set to? Is "Cbrs Data" on or off?

      de0u All apps work on Wi-Fi. I was actually able to resolve this by adding a new APN VZWINTERNET to replace the default TRACFONE.VZWENTP. Not sure if maybe it has to do with Verizon buying Tracfone or what.

          JohnnyBravo Do group chats/MMS messages work correctly for you on VZWINTERNET? I had this same issue, and for me VZWINTERNET resolves the mobile data issue, but then groupchats don't download (I don't even get a notification)

              16oberryan They don't work on Signal, but I had just been attributing that to Signal dropping MMS support. I'll have to test on the default messenger app.

                JohnnyBravo I, too, have spent many hours with Tracfone only to get nowhere. At least I'm not alone. I'd like to get it working, but at this point, I don't know what to try...
                I don't even know if this would be an issue with Tracfone or with GrapheneOS

                    I did initially, but then I bought a new sim when I noticed mobile data wasn't working (and Tracfone support said I would need to get a new one). And then. of course, I had the same issue with the new sim...

                      16oberryan I think I fixed it. For the APN VZWINTERNET, set:

                      MCC 311
                      MNC 480
                      APN Type default,supl,dun
                      Bearer (check these) HSPA, GPRS, EDGE, eHRPD, UMTS, LTE, HSPAP, HSDPA, NR
                      MVNO type GID

                      Leave other fields alone.

                          JohnnyBravo FWIW those match my "real Verizon" settings, except of course for MVNO.

                            JohnnyBravo That works! Thanks so much! It's almost frustrating how similar that is to something I've tried before. So similar, in fact, that I'm starting to wonder if I just forgot to hit save after editing the apn settings or something dumb like that.

                              JohnnyBravo These APN settings work for Spectrum Mobile, too. I’m on a pixel 4 fwiw. Thanks!

                                I'm having this issue, too (Tracfone mobile data not working on a Pixel 8a with Graphene), and I have no idea how to change APN settings. Can anyone by chance point me to beginner-level instructions on how to do this?

                                  obidk settings - > network & internet - > sims - > tap on a sim - > access point names - > tap on the APN

                                  Please note that the APN types selected (or not) will expose (or not) various fields for you to change.

                                      I lost mobile data after most recent 2024120900 build install. I still have cell coverage and sms and calls work but no data.

                                      I tried multiple things found on these forums with no luck. It does work when verizon total wireless sim put back in Iphone. I want to try this APN setting change but fields do not look the same as in post above, ie there is no MCC or MNC block. Any pointers?
