I just got my supposedly “5G ready” new iD SIM (a SIM only) SIM and I find that my up to date iPhone 12 is only showing the iD signal as 4G.
I have moved to different nearby areas - all of which are supposed to have excellent 5G coverage - but that does not improve matters nor did powering off/on the phone in those locations.
I have since read that iD doesn’t actually currently support 5G on iPhones.
Is this correct? Or is there something a phone user is supposed to do to get their 5G “ready” SIM to actually work with 5G?
