Whose bright idea was it to suggest our telcos to take down 3G network instead of 2G first is a failed decision. At least UMTS voice calls were much more relaible back then instead of 2G.

Not sure if this is 100% accurate but I think the reason is that the new TNB Smart Meters runs on the GPRS network, which is 2G....

These China branded phones very few of them made it into Maxis VoLTE and VoWifi compatibility list in time many will become eWaste soon even though thy support 4G networks.

Actually I poked around on some Xiaomi phones before in their modem config files

I noticed on older phones (Mi Max 2) only profile is for YTL (Yes 4G)
On some slightly newer ones (Mi A2), got profile for U Mobile

Only on rather recent phones that get updated (such as Mi 9T), got profile for Maxis.

On some newer models you can access a hidden config tool to force a profile from a different carrier and it might work.
Otherwise you're on the default "other" profile which might not work for your carrier.
For me on U Mobile and Mi Max 2, no VoLTE.
And no modem config tool either on this sadly.
Unless you want to go system file modifying and modify modem files (at your own risk), older phones are not gonna get volte sadly.

But with that said a part of the blame is also on the Chinese oems not updating their phones.

You need to root your phone to gain access to your phone's system file to modify those changes using developer toolkits. It'll void your warranty and risk bricking it. Also all your e-wallet and financial apps will be blocked. Some apps you can hide your root access with Magisk but security is questionable.

My Chinese phone is not an OEMs it's a Lenovo aka Motorola. It uses stock Android with very little bloatware. I would say clean ROM and efficient.

I think I'll consider modding someday
