Hi,

I use Dual Sim in S22 Ultra.

I use SIM2 just for calls, no data.

SIM1 is my main sim and I use it for everything, including mobile data.

Whenever I receice a call to SIM2, SIM1 loses mobile data connection. This happens immediately when the phone rings before I answer it and the mobile data stays disconnected until I hang up the phone.

I have tried many solutions:

Cleared SIM cache

Reset network settings

Reset phone settings

Changes SIM slotes

and so on...
