Network Issues

[L25Jl]

I have S23 Ultra, based in the UAE. Also the one UI 8.5 update, then followed by what it looked like a security update, now I am facing the issue, no Mobile Network coverage at all, it is between "emergency calls only" and 1 bar of coverage, with data not working (even though it shows 4g/5g sometimes) and even WiFi connection is not stable. Done everything that was advised on Samsung Members forum till the issues persist. 

Be advise on how to resolve this permanently
