Update to ONE UI 7 - Mobile Data stop working after few minutes of power on - Free operator in roaming

[maledetticinesi]

Hello,

after updating my S21 to One UI 7 I got a mobile data connection issue with French Free SIM card in roaming.

Restarting the phone the mobile data connection works well, but after few minutes stop working. Note that before ONE UI 7 update the smartphone worked like a charme.

I already try to:

- turn off 2G connection,

- wipe cache partition,

- turn on/off the smartphone, and

- reset network configuration.

Someone already tried a factory reset?

Thanks

Try manual network selection although it sounds more like roaming network issues

The issue starts after the update to ui7. No problems before...

I've been on at them in chat for 2 days now and told them it needs scrapping and not to force other rubbish on us without asking for permission
