Bug Description

When switching the network mode to 4G only (LTE only), I cannot make or receive voice calls.
Switching to Prefer 4G (Prefer LTE) resolves the issue.

Suggestion

Replace 4G only with Prefer 4G as the default option.

If 4G only must remain available, provide an option so the user can choose the most suitable setting for their use case.

Steps to Reproduce

Switch to 4G either through the app or tile
Try to make or receive a voice call
I doesn't work
Switch to 5G or Prefer 4G
Try to make or receive a call again
It works

Expected Behavior

To be able to make and receive voice calls independently of the mobile network state.

Actual Behavior

When 4G only is on, no voice calls can be made

Network Type Affected

4G/LTE
