do mobile phone calls go over 4g or I need to have gsm?
Do mobile transmitors emit all signals like edge hspa lte.. or just 1 ? why do we even need 2g and 3g anymore then
>why do we even need 2g and 3g anymore then
Because the majority of phones out there (Android shitphones) don't support VoLTE.

They do in Europe, India and Africa. Don't know why Asia, US and Australia cannot get their shit together.

Australian here. We're about to shut down our 2G networks. All our MNO's have supported VoLTE since late 2014. Our shit is quite together thank you very much.
