8.1 Oreo OTA update no cellular data

[Munchy1]

I recently updated to Oreo 8.1 a couple of days ago and everything works fine, but the one exception. I can not get cellular data, but i can make calls and send text messages.

Things i have done trying to troubleshoot to no resolve:
I got a new sim card from AT&T, I have also checked APN settings (checked out okay), I have factory reset the phone.

I gratefully appreciate any help and thanks in advance.

Current Software:

Android Version 8.1.0
Security Patch level: February 8, 2018
NON Root phone.

You have 2 choises. You can A: send the phone to razer or B: flash factory images after unlocming the bootloader then relocking the bootloader after done flashing.

Thank you for the reply. I tried option 2 to no avail as now I'm on to option 1.

I am having a similar issue. After updating to 8.1 I am unable to receive cell service as well. Can not call, text, or use mobile data..
In my case I am unable to edit the APN settings as it will not save for whatever reason.
On At&t as well.

I was speaking to @threeuKSupport on twitter yesterday and they are saying that theres some issues with the build that Razer sent out but couldnt say what the issues where so maybe mobile data connections where one of them.
