With an airalo esim, how do you switch back to your normal carrier sim? Can you switch back and forth between the esim and the existing sim incase you need to make a call on the sim?
Both SIMs essentially function together – so you can decide which SIM you want to use for calling, and which one you want to use for Data.
Additionally when making a call it defaults to the SIM you selected for phone calls, however does also give you the option to modify that before making the call (on an iPhone it shows up at the top, usually your standard sim is called “Primary”)
