The status bar icons at the top of the screen show the strength of your two operators’ signals. 

Other status icons appear when you open the control centre.

When operator 1’s line is used, the “No service” message appears for the other line. The status bar indicates that operator 1’s line is using an LTE network and that operator 2’s is using Wi-Fi calling.

When the “Allow cellular data switching” option is activated, the status bar indicates that operator 1’s line is using an LTE network and that operator 2’s is using mobile data for operator 1’s line and that Wi-Fi calling is on.
