I have a brand new S21 Plus purchased a week ago, it was working fine with VoLTE toggle visible. After the November patch update it is gone, can't see, hence cannot make calls. Right now it is like a paperweight on my table and I had to switch back to S9+ again to make calls.
Looks like it is an issue with S21, if not resolved quickly by Samsung I have to return it to best buy.
Does anyone have a solution?
Done all of those.... Anyone has the same problem?
for me this all happened after beta 4 install, this patch broke it.
I saw a couple of posts with the same problem, but they say it got fixed by carrier service, no such luck in my case though.
