iPhone 17 eSIM: Germany on the Way to a New Era

With the iPhone 17 series, Apple is changing the mobile experience: the standard and Pro models still keep the SIM slot, but the iPhone 17 Air is the first model without a physical SIM card. Instead of using plastic, you manage everything digitally. Apple is making the direction of travel clear: eSIM is set to become the mandatory standard for future models.

The iPhone 17 Air makes this step especially clear: its slim design does away with the SIM tray and focuses on a radically digital user experience.

Why is Apple making the Air eSIM-only?

With the Air, Apple is taking a major step in Europe: no physical SIM anymore, only eSIM. In the USA this has long been reality, and expansion to Europe was only a matter of time. For you, that means: contracts can be activated digitally in just a few minutes, and switching between plans is easier than ever.
