Do I have an eSIM or physical SIM?
Here’s how to check whether you have an eSIM or physical SIM:
iPhone users can head to Settings > Cellular > SIMs. Phones that support eSIM will display an “Add eSIM” option. If there is only a physical slot for a SIM card, then that is what your phone is currently using.
Android users can go to Settings > Network & Internet > SIMs. If your phone supports eSIMS, then an option to add an eSIM will appear.
Some phones have the capability to support both eSIMs and physical SIM cards, which allows users to take advantage of dual SIM functionality for having multiple numbers or data plans.
