[PLUG-TALK] Android phone question

Handling normal calling over Wi-Fi+cell is handled by your calling app on
the phone through operator setting. It  has nothing to do with bands and
signal strength - that is related to the radio modem - the calling app just
sends data - either through the cell modem or via general IP.

It seems that your operator doesn't support it otherwise having WiFi on
would just route the call data through IP.

My operator, and the phone, supports it. So, all I need is cell signal or
WiFi and calling just works as long as I have some data service working.

If my operator would not support that. I would either get VoIP through
Google, Skype, or some other VoIP service out there - transfer my number to
them and use their App on the phone, PC, ... to get the calls everywhere
regardless of the cell signal situation.

I thought that some of the folks with wonderful VoIP experience would join
the discussion. I guess, something in the post discourage them. Perhaps it
is this radio amateur operator speak , quite irrelevant to the modern VoIP
calling.

Voice and calls is just data these days. If someone pretends otherwise,
they are just segmenting the market, by making things look difficult.
