Hi I’ve been having issues with my network connection since sometime last fall. Most of the time my device is stuck on EDGE (2G network) even when 4G and 5G networks are available.
I think it was caused by a Google Fi app update but I’m not sure. I’ve tried to work with Google Fi support like 3-4 times and they are very unwilling to do anything. I’ve narrowed it down to an issue with VoLTE configuration. When I don’t have the Google Fi app installed things don’t work until I enable 4G Calling in the sim settings. At which point things seem to work correctly. However once I install the Google Fi app that setting disappears and as far as I can tell it seems like VoLTE (which I think is the same thing as 4G Calling) is disable on the device. I’m pretty sure that Google Fi requires VoLTE and the app should force enable it. However for some reason that fails to happen.
Does anyone know how to override this behavior to get 4G Calling enabled so that my data can work? Is this something that could be patched into the Fairphone OS? Is there some way I can better get through to Google Fi so they can maybe fix their app?
