4g switching to 3g during calls

Hi I recently signed up to boost prepaid I have good strong 4g reception but when I do outgoing calls it switched to 3g ? The same happens with incoming calls? I notice I have no volte function either ?

I purchased this s8 plus phone from Vodafone Australia I used to have no problem with calls or with volte could it be a firmware restriction ? I was told by boost this was normal ?

Re: 4g switching to 3g during calls

The carrier firmware has the connectivity details for VoLTE.

Generally carrier devices will only work optimally on the network whose firmware was initially installed. The exception being the iPhone and Pixel ranges which use a single firmware but with carrier updates seperate.

From what I have seen previously only Samsung themselves are able to flash the carrier firmware and change it but I have heard of some people having it done and others being told it can’t be.
