iPhone XS, iPhone XS Max, iPhone XR, and later feature Dual SIM with a nano-SIM and an eSIM. An eSIM is a digital SIM that allows you to activate a cellular plan from your carrier without having to use a physical nano-SIM.

Use one number for business and another number for personal calls.
Add a local data plan when you travel outside of the country or region.
Have separate voice and data plans.
