My P9XL has the wifi calling option, so if that is what you are referring to, it is already available for pixels. Should be no different for the pixel 10s.
While there is no VoLTE option, I believe it is automatically enabled as I am able to make phone calls while on data (without wifi) and browse the internet on a 4G connection while on a phone call

Bought in shopee google pixel store says today only ship out receive tomorrow or latest by sunday cant wait

is pixel 10 good or better wait another year to iron out all the flaws?

i mean not just only number performance bump up lol

i am still using pixel 5 and so far still okay. not really lag as in older nokia phone that running androind one last time

also i saw the rumors of 10a, what the hell is google thinking, what is the point to sell 10a if it is same as 9a lol
