iPhone 17 eSIM: Germany on the way to a new era
With the iPhone 17 series Apple is changing the mobile phone experience: Although the SIM slot remains the same in the standard and Pro models, The iPhone 17 Air is the first model without a physical SIM card. Instead of using plastic, you manage everything digitally. Apple is thus clearly showing where development is heading — in the foreseeable future, eSIM will become a mandatory standard for future models.
Especially that iPhone 17 Air illustrates this step: The slim design dispenses with the SIM compartment and thus provides a radical digital user experience.
Why does Apple choose eSIM-only for Air?
Apple is taking a big step in Europe with Air: No more physical SIM, just eSIM. This has long been a reality in the USA; the expansion to Europe was only a matter of time. For you, that means: Contracts can be digitally activated in just a few minutes, and switching between plans has never been easier.
Benefits and potential challenges of the iPhone 17 eSIM
The eSIM offers several advantages — especially with Air: more space inside for a slightly larger battery, additional security as the card cannot be removed, and the ability to save up to eight eSIM profiles. Ideal for frequent travelers or business users.
Important: All iPhone 17 models support eSIM, but only the air is completely dependent on it. Anyone traveling abroad should check whether the destination country supports eSIM.
