I think best is to check with your service provider before buying a phone especially those AP unit, not sold in Malaysia, extremely rare brand with no service centre and no sales centre in Malaysia, there will be a lot of issues as phone makers usually handle their software by country/region ... they won't care if you buying something illegally somewhere ... and operator will not be able to do anything as well ...

Have you tried the P#### method, edit the volte file

Kek just found this thread. Was gonna grab a cheap jepunis sekenhand unit for the more up-to-date android and NFC but then realized it doesn't have a bunch of compatible features like decent voice calls. Thanks guy for saving my money. Guess I'll either go with an older ipong or the S10. My current phone has Volte but its version of android is so old that some of my apps can no longer update. I just need something that's at least 5 versions ahead of what I've got so I can use it for a few more years. That's what I get for buying Huashit I guess...

Get A52s/S20FE 5G/Note 20 if you want superb updates

Otherwise get A### Zenfone 8/8 Flip/9 or ROG Phone OR S### XPERIA 1 III/IV if you want sturdy build

I have no idea what you were smoking when you wrote that. Defeats the whole purpose of buying a cheapass temporary phone if I were to spend 2k for a new one. I might as well just bite the bullet and buy an iPhone instead and have pretty much have guaranteed updates for the next decade.
