Re: Voice on Nokia 225 no longer working.
I'm assuming that Kai OS devices still work since it's my understanding that the Nokia 2780 and 6300 are still functioning. That may be a wrong assumption since I don't have any Kai OS devices. As for what changed, I don't think it's anything in your handset that changed, but rather that Google made a change to their VoLTE specification that either intentionally or unintentionally blacklisted all handsets that don't have a specific something in their ROM which allows it to continue to use VoLTE. What that specific something is, or what it does, I don't know. But whatever this is, it would be good for T-mobile tech support to tackle this issue and let the customers known as there are a lot of handsets out there that are 4G/LTE/VoLTE capable - and were working using these protocols on the T-mobile network until just recently (long after the 3G shutdown).1Ver0likes0ComentariosRe: Voice on Nokia 225 no longer working.
I think the poster above who said that Google changed something in their VoLTE implementation may be correct. The issue is being discussed here on Reddit and the person who started that thread and a commenter has identified two Android handsets that (a) lost VoLTE (on Android 7) and (b) didn't have VoLTE or IMS registration on Android 9 but saw it begin to work when he upgraded to Android 11. From that discussion "So my guess is the speculation is correct. Google has changed something that prevents older Android handsets and non Android/iOS/Kai handsets from using VoLTE." It's probably more correct to say older Android versions, but what exactly changed?2Visto0likes0Comentarios
