Hey there and welcome to the Samsung UK and EU Community Forum

Please note this is not Customer Service.

Can you please perform a Reset MOBILE network settings on your device.

You won't lose data.
Your network will automatically update your APNs.

Reboot your device.

Did this many times and nothing helps with many sim providers

Do a diagnostics test within the samsung members app. What results do you get?

[testeatuk]

Showing all ok not showing problem with network even it showing cross on network . This is strange

[johnz237]

Yes- how strange. Adding onto the suggestion from another user. Have you attempted to clear cache partition?

connect your phone to A PC then Turn off the device.
Press and hold the Volume Up key and the Power key.
Once the Android Recovery screen comes up, release the buttons.
Use the Volume Down button until you are highlighting 'Wipe cache partition.'
Press the Power button to select 'Wipe cache partition.'
Use Volume Down to highlight Yes.
Press the Power button to confirm the action to
clear the cache.
Wait for a second as the system wipes the cache.
Press the Power button again to reboot the device.

If this still doesnt work- it may be time to contact customer support directly

Yes did but nothing change . Definitely problem with ui 6.1

[testeatuk]

Everything is done nothing helps . I think it is problem with samsung update and handset hardware issue as 5g in place and hardware is not supported even it is mention its 5g. We need proper solution for this

If it was a problem with One Ui6, it would affect all users. It isn't.

So it is device specific..... maybe a configuration issue with your router?

I also checked same sim with note 20 and perfectly working fine and making call ane receiving call its definitely update issue time to take action as many users have same problem after update
