One UI 6 update not able to make phone calls

[vatsag]

I have enabled the option to download automatically the updates in my A53. However ever since the recent update One UI 6, my phone has started behaving weird. Sometimes I am not able to make phone calls. The internet stops working all of sudden. Is anyone facing such issues ? What is the possible resolution and any hotfix is planned ?

Could do with some more info such as exact phone model. 5G or 4G. Esim or Physical SIM. Where are you based? Network provider. Troubleshooting methods already tried.

One thing to try as a start is

Turn off your device. Take your physical SIM out, give the gold contacts a rub and put it back into this device.

• 5G
• Physical SIM
• Location : Denmark
• Network Providers : Lycamobile and Vodafone 
• Tried removing and cleaning the SIM tray and putting back to the device.

Can you try

Settings>connections>mobile networks>access point names. Choose your data plan. Click three dots upper rh screen, click reset to default.

This didnt not help either. I changed to a new SIM this also doesn't work. The new SIM works on a different phone
