@ashutoshthakur Glad to hear that. Congrats! I am trying to get the same update but I checked system updates, and there are no updates for me. Any tips on what conditions I need to replicate to be able to get that update? Thanks.

Thanks for the reply. I sent the error report. Also, note that this is not a part of the "beta program". This problem is happening with the One UI Stable release that I received. Also please reply to the following thread which contains more information on the same issue. https://us.community.samsung.com/t5/Galaxy-S21/DON-T-BUY-S21-Series-Phones-if-you-want-use-it-outside-US/m-p/2115097#M42243

Thanks for pointing me to the thread. It didn't show up when I searched Google for "S21 Ultra OneUi 4.0 Update Calls not working".

Thanks for the answer. I will try it, but as a software developer myself, I don't think it will work. Also, I don't think contacting my carrier will work here since there is nothing wrong with my carrier. The same SIM used to work on OneUI 3.0 yesterday. I think Samsung has a bug in One UI v4.0 here. There are many tickets reporting the same issue. 1. https://us.community.samsung.com/t5/Galaxy-S21/VoLTE-Not-working-after-Android-12-One-UI-4-0-Update/td-p/2114776 2. https://us.community.samsung.com/t5/Galaxy-S21/Volte-not-working-after-One-Ui-4-update/m-p/2115064#M42227 3. https://us.community.samsung.com/t5/Galaxy-S-Phones/Volte-and-wifi-calling-is-not-working-in-one-UI4-O/m-p/2115065#M85897 What do you think? For all of the above people, with OneUI v3.0, everything was fine. It is OneUI v4.0 that is causing the problem IMHO.

I am curious if porting my physical SIM to eSIM will work or not? What do you think?

I bought my phone in the US but now I live in India. Since it is the globally unlocked version, it used to work in India just fine. But after OneUI 4 update, phone calls and SMS have stopped working. Please look into this as it is a big problem. It basically makes the phone unusable.

I also have the same problem. Are you based in the US or another country? Just curious. I have US-based unlocked S21 Ultra but I am using it in India.

I am in the same boat as you. Calling not working for me after One UI 4 update. Do you have the Snapdragon version by any chance?

What do you mean brother? Reset device? I don't see an option to reset settings. Update - I reset my network settings. Still not working.
