TL;DR: Installing an eSIM on iPhone is quick and digital. Most modern iPhones, including the latest iPhone 17 models, support eSIM.

To use an eSIM, your iPhone must meet the following requirements:

eSIM-ready hardware: Your iPhone needs an Embedded Identity Document (EID) to support eSIM.
Carrier unlocked: If your iPhone is carrier-locked, you might not be able to activate eSIMs from other providers.

Activating Your eSIM on iPhone: Getting Connected

Once added, you need to activate and configure your iPhone for proper use:
