Find wireless carriers and worldwide service providers that offer eSIM service on iPhone - Apple Support

An eSIM is a digital SIM that allows you to activate a mobile data plan from your network provider without having to use a physical nano-SIM. Find out which wireless carriers in your country or region offer cellular plans on an eSIM, either activated by eSIM Carrier Activation, eSIM Quick Transfer, or other activation methods. Many carriers also support eSIM activation on prepaid plans, if you want to use a local line while traveling internationally. Worldwide service providers also offer eSIM plans in over 190 countries and regions to use while at home or when you travel. If your iPhone is unlocked, you can also use eSIM plans offered by other carriers.
