Auto Data Switching:

Switch to another SIM for mobile data if the preferred SIM can't connect. 

If Wi-Fi Calling is on, SIMs will also be able to make and receive calls when they're out of network range. The calls will go through the mobile data connection of another SIM.

I've noticed that the Samsung Galaxy S22 series has a limitation with the Backup Calling feature when using dual SIMs while the second SIM card is in roaming. Interestingly, this isn't an issue on devices like Google Pixel and iPhones, where the feature works seamlessly even when the second (e)SIM is roaming. This discrepancy in functionality is quite puzzling and pointless. Do you know if there's hope for Samsung to address and rectify this issue in future updates? It would be a significant improvement for users who frequently travel or rely on dual SIM capabilities.

I need that feature too. This feature is need when roaming and samsung is ban to use it when roaming. You should at least give and option in a menu for the people who needs this service when needed. iPhone and Pixels has no such restrictions why Samsung is doing that.

Is this an existing feature, or one you would like to see incorporated?  I don't see it anywhere on my US variant S22 Ultra.
