You must on 4g networkWanna clarify on this… for this volte roaming, say when i’m overseas and wanna call a local number there or call back sg number, regardless a fixed line or mobile number, i just go my contacts and call as per usual? Any requirements on phone/hardware? I’m using the $8 one on my old iphone 11pro max. It’s a spare line that i would bring along during hols just for this overseas calls contingency… although i’ve never had to use it so far…
Last time i went vietname many area no 4g only 3g
Can’t receive and make call
