Hi, I’m Anna – a frequent traveler who has tested more than 20 eSIM providers while exploring the world. When the iPhone 16 was released, one of the first questions I asked was: “Do iPhones 16 have SIM cards or are they eSIM-only?” If you’re planning to buy the new iPhone or already own one, understanding its SIM setup is crucial – especially if you travel abroad.

The short answer: In the U.S., iPhone 16 models are eSIM-only, but in many other countries, they still support both physical nano-SIM and eSIM. Let’s dive into the details, why Apple is pushing this change, and how you can make the most of eSIMs when traveling.

iPhone 16 SIM Card Setup: U.S. vs Global

iPhone 16 in the United States

• No physical SIM slot at all

• 100% eSIM-only (like iPhone 14 and iPhone 15 US versions)

• Supports multiple eSIM profiles (great for frequent travelers)

iPhone 16 in Europe, Asia & Other Regions

• Dual SIM: 1 nano-SIM + 1 eSIM

• Perfect for those who still want a physical SIM as backup

• Allows you to combine local SIM + travel eSIM seamlessly

As someone who often switches between countries, I personally love the flexibility of eSIM. With just a scan of a QR code, I can activate data instantly—no more fumbling with tiny SIM cards on the plane.

Why Did Apple Remove the SIM Card Slot?

Apple’s move toward eSIM-only devices has three main reasons:

1. Convenience: No need to buy a SIM card physically—just download one in seconds.

2. Security: If your iPhone gets stolen, no one can remove the SIM card to avoid tracking.

3. Space-saving: Removing the SIM tray frees up space for more battery or hardware improvements.

💡 From my experience using eSIMs, the real benefit is when traveling. Imagine landing in Paris and activating data in 2 minutes without searching for a local store.

If you own an iPhone 16, eSIMs are your best companion. Here are some top options I’ve personally tested:

📌 Personally, I’ve used Airalo for over 10 trips across Europe and Asia. Their data speed and customer support were consistently reliable. If you want peace of mind, I’d start with Airalo or Nomad.

How to Activate eSIM on iPhone 16
