mickey10021I'll swap my sim, and if it's still not working I'll change providers instead. I don't like forced obsolescence, and I won't stand for it from any company
Since AT&T need to whitelist Rog Phone 2 first. There is nothing you can do. You have to buy new device instead.
Even Asus updated modem to support it but AT&T doesn't add device to the list so it's pretty much game over.
Same goes as Zenfone 6
ButterChicken4G data works fine on this sim, so I'm pretty certain I'll just need to swap to T-Mobile/Mint Mobile (since I just got a Mint sim and it works flawlessly)
iphone 5s is 3G phone
You must talk once from ur sim card provider
Or try to use same sim card in another phone which supports volte
If that sim works then the problem may be from DEVICE SOFTWARE
Everyone except tencent edition
Have same GLOBAL ROM
And Volte working in my phone since beginning
