SIM 2 Bug after updating to Android 10. Losing reception every now and then.

Okay, now this one is very annoying. After updating to Android 10, my SIM 2 network just disappears every now and then. Everytime I've to disable the SIM 2 and then re-enable it again in order to get the reception.
I keep my personal SIM in Slot 2 and now I'm losing all the important calls due to this stupid bug. Please fix it. This issue was not present in Android 9.

I use two sim cards both in Android 9 and 10 and I don't have this issue. It could be device/configuration specific and not related to the Android 10 update.
What happens if you swap your sims? Still only problem with SIM slot 2?
Yep, still the same. And this issue triggered only after I updated to Android 10.
Facing the same issue of Sim 2, frequently during the call phone goes into flight mode. This is surely after android 10 update
Today my phone restarted twice just after I finished a call. This is such a poorly optimised update. I hope the motherboard issue is not back. I've already got it replaced once.
Look at SIM 2's network. This is what happens every now and then. Now I'll have turn SIM off and back on again to get the reception. It's such a nightmare.
Have you factory reset your phone since the Android 10 update? It can be tedious to transfer all your data and contacts, but that tends to be a really foolproof way to eliminate software issues.
Same issue with me too.. whether it's my sim 1 or sim 2 when i use data on it I lose reception
i have similar issue but only with data... data is disconnected on both the sims and thn i have to switch between different apn's to make it work again..
Same issue here.
Using 1 sim only seems to be much better. Is it same for others here?
I take for granted that you have all tried to restart your phone. This can solve a lot of strange issues.
This could also be a carrier bug. Which carrier are you all using?
Yes restarted multiple times.
In latest update problem is uniform across SIMs now. Tried with restart, swaping, disabling one SIM etc.
I am from India. Carriers: Airtel, Jio. Both support CA too.
