when ever i make a phone call my 4g turn to 3g anyone have this problem?
iPhone XS, iOS 13
Your phone will use 4G/LTE if it is available. It will use analog voice otherwise. Voice is called GSM; there is no 3G/4G, which only applies to data. If it switches to 3G that means that the carrier's network does not have sufficient capacity for VoLTE.
It sounds like your carrier can do voice+data, but it's still a network problem. Have you tried updating carrier settings? See this Apple support article-->Update your carrier settings on your iPhone or iPad - Apple Support
i can enter internet but after a period of time the internet will get cut off
so when i'm on call and i suddenly loose 3g and can't access the internet it means the carrier's network is at fault?
This is a matter for your carrier
is it volte? if so they have it.
Some carrier’s networks cannot do simultaneous voice and data.
There are no updates to carrier
when i call my 4g turn to 3g
