👋 Hi, I’m Anna, a travel enthusiast who has tested dozens of eSIMs across the world—from Europe to Asia and the Americas. If you’ve just upgraded to the iPhone 15, you might be asking the same question I did before my Japan–Europe trip: how many eSIMs can iPhone 15 have, and can it handle multiple travel plans easily?

In this review, I’ll share real travel experiences, answer this key question, and recommend the best eSIM providers (like Airalo, Nomad, Yesim, Maya, and more) so you can pick the right one for your trips in 2025.

👉 Quick CTA: If you’re planning a trip soon, I highly recommend checking Airalo’s travel eSIM store here or Nomad’s global eSIM options before your flight.

Does iPhone 15 Support eSIM?

Yes—absolutely! Apple has gone all-in on eSIM technology with the iPhone 15 series.

• US models: iPhone 15 comes with no physical SIM slot—you must use eSIM.

• International models: Most allow 1 nano-SIM + 1 eSIM, giving you dual-SIM flexibility.

This change might feel drastic, but as someone who constantly switches countries, I can confidently say it’s far more convenient than juggling tiny SIM cards.

How Many eSIMs Can iPhone 15 Store?

Here’s the good news:

• iPhone 15 can store over 8 eSIM profiles at once.

• In practice, I’ve kept 10+ eSIMs (Europe, Japan, USA, Vietnam, and a backup plan) without issues.

This means you can download and keep multiple eSIM plans before your trip—no stress at the airport.

How Many eSIMs Can iPhone 15 Use at the Same Time?

While you can store many eSIM profiles, you can only activate up to 2 eSIMs simultaneously.

Example from my travels:

• In Europe, I kept Nomad eSIM active for data and my home eSIM for iMessage & WhatsApp.

• When flying to Japan, I simply switched from Nomad to Airalo eSIM in settings—took less than 1 minute.

👉 So, the short answer to “how many eSIMs can iPhone 15 have?” is:

• Stored: 8+ profiles

• Active at once: 2 eSIMs

Why eSIM Is Perfect for International Travel

As someone who travels monthly, eSIMs have changed the way I stay connected:

✅ No SIM swapping – no tiny trays or lost cards.
✅ Multiple plans ready – install before departure.
✅ Instant activation – scan QR code, done.
✅ Cheaper than roaming – save 70%+ compared to carrier fees.

💡 Personal note: After trying physical SIMs for years, I now rely 100% on eSIMs. During my Southeast Asia trip, switching between Maya eSIM in Singapore and Yesim eSIM in Thailand was smoother than ever.
