Help! Cannot turn on mobile data while calling and messaging still working!

[EdwardSawhands]

This is regarding the Snapdragon Note 20 Ultra, USA version.

I got a Note 20 Ultra Verizone edition where I flashed an unlocked U1 firmware. I suppose the required software information can be seen from this screenshot:

The issue now is, as I have put an Indian Operator (Airtel) SIM in the mobile, calling and messaging facilities are working flawlessly, but I cannot turn on mobile data. The WiFi works fine, but no mobile data. The SIM Information looks like this:

Moreover, whenever I try to open the SIM Manager, these four dots keeps loading and the screen just stays there:

I haven't taken a screenshot, but in the next screen the Data Roaming Option cannot be turned on also, I was just looking and turning on/off here and there.....

This is picture of the drop down menu, I suppose it won't be of any help, still posting:

Please let me know if there is any way to solve it....... Also let me know if any other info is required, as I believe I might have missed posting something.....Thanks!

Before, I flashed this firmware, my software info was like this:

And, now after flashing the U1 it is like this:

I see the VZW (Verizone, right?) is still showing in the Service Provider Software info..... Have I f it up somewhere during the flashing? Should the VZW still be there after flashing the U1 version?

Yes, it is Verizon and it is not supposed to be there. You should see INS for Indian firmware/ SIM.

The problem is they released the Exynos version in India! I suppose I cannot flash Exynos version on Snapdragon, right? Also, the Indian rom had dual sim while this one is i physical SIM+ E-Sim.

Ok, little update.... I flashed the phone again with a VZW Android 13 firmware, and now the mobile data with my Airtel SIM is working flawlessly, even with 5G!!! But guess, as I'm not with a VZW SIM, the set will not receive any update now!
