backup calling using secondary line's data for primary line's (almost unlimited) voice and text
I need to simulate backup calling when i go to india and plan to use secondary lines data for primary line calling. i can not change network selection for primary line no matter what i do - on either iphone 15 or pixel 9a
how do i go about? I tried pixel IMS but i am unable to simulate this in the US as I can not change network selection for primary line
