VoLTE and wifi calling not working on unlocked S21, S21+ and S21 Ultra

[Baazigarg]

Just putting this post out here to let the team know that we still can't make calls or recieve messages on our unlocked phones bought directly from samsung.  Are you guys working on it? atleast acknowledge the problem!

what have other people with this issue done? Can someone guide/ help me to downgrade my phone?

Did this get solved? I'm facing this problem after the latest software update

[Baazigarg]

not at all. samsung forums are filled with similar complaints but they haven't even properly acknowledged the issue yet

I took the extra step and got my sim changed to an esim service. Now this sim won't work in any other phone either

[Baazigarg]

thats sad. the only option for me is to either port to airtel(I've heard those still work) or downgrade to one ui 3.1

Can you please tell me if downgrading is something simple and can be legally done or is some complicated process like rooting required?
