Hi, How all can I get HD Voice/ HD Video Calling on my unlocked Samsung S21 Ultra phone? It's already enabled on my acount. I know that your suppossed to have a Verizon version phone but I didn't know that before. Their must be a way for me to get HD Voice/HD Video Calling on my unlocked Samsung S21Ultra phone? I see other people have it on their unlocked device so I know their's a way to get it on there also I was able to get everything else Verizon on there.
Please Help I Would Really Appericate It
