No Service after One UI 5

After updating both of the SIM cards in my phone don't work, more often than not. The text it reads  is "No Service" and there's a 🚫 sign along the top next to the battery icon.  This happens when WiFi is off and I want to use Mobile Data - so  now most of the time my phone is only usable if on WiFi.

Tried rebooting

Tried reset network settings

Tried aeroplane mode

Tried remove and reinsert SIMs

Tried deleting cache from recovery

Tried installing November patch

Any other ideas? Only thing I haven't done is a factory reset

 

I literally had zero issues with signal before the update - it worked 100% fine

I think you will have to hit with a factory reset
