I downloaded my GigSky plan but now my phone number doesn't work. Why not?

Make sure that you have not selected your GigSky eSIM plan as the Default Voice Line. Doing this will deactivate your voice line.

Go to Settings > Cellular.
Check that Default Voice Line is set to your "Primary" SIM/eSIM and not your GigSky eSIM.
If it is set to your GigSky eSIM, tap Default Voice Line and select "Primary".

If you have any further questions, please contact GigSky Support at support@gigsky.com.
