eSIM technology has made it easier than ever to stay connected without inserting a physical SIM card. Whether you’re traveling abroad, switching carriers, or using a secondary line for work, an eSIM offers flexibility and convenience.

What Is an eSIM?
An eSIM (Embedded SIM) is a digital SIM built directly into your iPhone. Instead of inserting a physical SIM card, you simply download your mobile plan from your carrier or eSIM provider.
An eSIM lets you:
- Activate a mobile plan digitally
- Use multiple phone numbers on one iPhone (supported models)

- Easily add travel data plans
- Reduce the risk of losing or damaging a physical SIM
Many modern iPhones support both a physical SIM and one or more eSIMs, depending on the model and region.
