@oya-g said in Japanese!!:

Channel Update → 20.04Development has Japanese. My device is Pixel3a, so it is 4G compatible.

The "development" channel is maybe not meant for day-to-day use, as it may be buggy and/or unstable. So really looking forward to japanese support arriving in stable.

Note that even with a 4G compatible phone, you will not be able to do any phone calls inside japan, as the 4G protocol stack does not by itself support telephony. It only supports data.

For telephony, you need VoLTE support, which is quite a messy affair, as it requires various firmware and software components to cooperate properly for calls to be routed over the 4G data layer (i.e. as VoIP call). UBports does not support that currently.
