Yesterday, I updated my Zenfone 4 with the Android 9 Pie Beta, that was released at Asus website this week. It was all fine and perfect, until I went out today and tried to use my 4G. It just doesn't work anymore. The network mobile data function doesn't even turn on. I recorded my screen to try to show what is happening, because I have no idea what to do to solve this. :( https://youtu.be/h6pTJOev-PY

The problem, in my case, isn't with the carrier, is the OS. I tried different SIM cards to make sure it wasn't a phone provider problem. Even with other cards from other carriers, I was still unable to just turn the mobile data function on 😞

I'm also using Android Beta Beta, try to format. I updated normal without formatting, it worked everything ok.
