Hi Jorel
Thank you for your asking. Kindly try some stay-at-home troubleshooting tips below:
1. Please try to reset Network: Settings>System>Reset>Network settings reset
2. Which version did you update from? Did you perform the cross-Android update before the issue appear?
3. Please try to enter "Safe Mode". If the function works well in Safe Mode yet the issue remains out of Safe Mode, please check on any disturbance from the installed 3rd party apps.
# How to enter and exit "Safe Mode"
[Phone/Pad] How to Enter and Exit Safe Mode? | Official Support | ASUS Global4. Last, please try "the Factory Reset" 
Setting>System>Reset>Factory data reset
Please note that once the Factory Reset is completed, all data, apps, settings and personal information will be deleted.

I've tried all those troubleshooting tips including factory data reset but sadly "No Service" status re-appears. And here I am, started over again.
