Losing mobile Internet during calls ...

[Easty]

This has been happening on and off for a while but was limited to vodaphone line in sim1 , sim2 ee wasn't affected but today its happening which ever sim is selected for data , I have dual sim turned on so its not a case that the particular network has not signal as it should switch to other sim for data and as soon as call hangs up Internet connection magically reappears !! I've had a new sim from vodaphone , factory reset phone , reset network settings , had new apn settings , this was limited to vodaphone but not anymore .

Sent multiple reports via feedback on here but they never help .

Done diagnostics and it's says sim cards all ok ?

I used to get this on my old S10 with a plusnet sim which used the EE network, moved to GiffGaff which uses O2 and haven't had a problem since, don't know if it was a sim problem or network.

I thought originally it was vodaphone issue but it's now happening on lyca mobile sim which is ee so must be software issue ?
