Question X90 Pro Plus Network Issues?

[pwrdbykyank]

Just wondering if anyone else might have had this issue I'm having and if there is any fix or work around for this. So I imported a Vivo X90 Pro Plus China variant and am currently using it in the US. I originally was using Verizon on it but was having network issues. Would work for a week or so (4G data,text,voice all worked), then would go to no bars and no service and would not re-connect with the network. I would have to remove the sim card, and re insert it multiple times or activate a new sim card and put it back into the phone for the phone to re connect and show signal bars and work again. So I assumed its just Verizon thus switched to a T-mobile sim and started using T-mobile with the device. With T-mobile worked better, got 5G instead of only 4G and everything was smooth for about 3 weeks. Then again I am having this same issue. Every week it drops service and says no service, I have to remove the sim card, insert a completely different sim and remove that sim and re insert my active sim for the phone to re establish and activate with the network.

SO the only thing I can think is that either the phone software somewhere is rejecting and blocking the sim or network after a while for some reason, or that the carrier (tmobile and verizon) are rejecting the phone being on their network and kicking it out. But if that is the case, why does it work again when I remove the sim, insert a different sim and re insert the same active sim back again. Makes me lean toward a software lock or something.

Any ideas? Thanks guys.

Im now in US too, currently running on mint and i didnt see any problems with network issues, most of time in on wifi but every time i need data it works fine. Only difference is im running european sim on slot 1 and us on slot 2.

oh, hmm not sure what could be causing this issue for me. I'm thinking maybe one of the installed Chinese apps are interfering with it but not sure.

I'm on mint as well (uses T-Mobile network).

Never had any network issues.
It might be worth trying to restore the phone and try the newer 2.6.4 debloat script as a baseline.

Then after that you can try removing some of the additional system packages like vivo store or vivo.pem (although the jury is mixed on whether it's useful to do that).

I may have to try that and look into it. I'm not too familiar with doing any rooting or running adb stuff (been years since I did that sort of thing) so worried I might mess something up rather than fix it lol
