My phone company is implementing volte and I have it enabled in my line, in fact when I put the sim on my sisters iphone or xiaomi mi 10 t pro's grandfathers phone I get VOLTE but on the s10's plus is impossible to get VOLTE.
I'm very dissapointed that xiaomi's and iphone( older than my samsung) are getting volte with yoigo but my samsung or samsung of my mother, not.
Is it planned to implement this on samsung on some point? I have volte with vodafone and movistar, but with yoigo there is no way
to sum up: xiaomi and iphone= volte on yoigo with my phone number, the same sim on s10 plus updated today != volte, a shame
