Installation of iodeOS on my pixel 7 went great! I was previously running GrapheneOS, went back to stock AndroidOS, now just installed iodeOS. I only have one problem. A major one really. I put my SIM card in the phone and it gets no cellular signal or connection. Wi-Fi works fine. Are there specific carriers, I’m FirstNet (a branch off AT&T), that don’t work with the OS specifically? ---

So the SIM is not activating? That is strange, have you confirmed settings in `System Settings > Network and internet > SIMs > your sim`? (mobile data on, APN correct, VoLTE enabled, etc)? ---

Yes. The phone detects the physical sim, shows the carrier and all the correct settings are enabled. It won’t connect to the mobile network at all. ---

I’m curious, does Android offer other networks/carriers if you choose “select manually” instead of “auto”? And are you able to connect to a different carrier? But watch out with mobile data as I don’t know your roaming conditions.. ---

APN says it’s not available for that user. Not sure what that means as it’s the only user freshly created on the phone. I attached screenshots so you can see the options within the sim/cellular options. ---

I haven’t seen this before but clearly something here is amuck. Are you able to tap “+” to create a new APN entry? And did you set up multiple user profiles in System settings, or maybe using a work profile (Shelter or other) or something like that?
