Why cant I find the volte setting in my phone. I was recently in the US on a add on plan to my canadian public mobile (Telus) account and the data and texting worked but no voice call. Public mobile said my phone was not compatible because it didnt have volte. The phone is a s20fe g5 from from an afterseller but it is branded at start up with at&t I have attached my options from my mobile options tab. No VOlte option
