Hi, I’m Anna, a passionate traveler who has tested dozens of eSIM services while exploring over 30 countries. If you own an iPhone, you might have asked: “How does Dual SIM iPhone work, and why is everyone talking about eSIM?”
The short answer: Dual SIM iPhones let you keep two numbers active at once—one physical SIM and one eSIM (or dual eSIM on the latest U.S. iPhones). For travelers like me, this is a game-changer. No more swapping SIM cards at airports or worrying about losing your primary number.

What Is Dual SIM on iPhone?
Apple introduced Dual SIM starting with the iPhone XS, XR, and XS Max. Since then, every new model supports it in one of two formats:
-
Most international iPhones → Nano SIM + eSIM
-
U.S. models of iPhone 14 / 15 / 16 → Dual eSIM (no SIM card slot)
This means you can:
-
Keep your primary number for calls & iMessage.
-
Add a second eSIM for cheap data abroad.
-
Switch between carriers without removing a SIM tray.
How to Set Up Dual SIM on iPhone
Setting up is simple and takes less than 5 minutes:
-
Go to Settings > Cellular > Add Cellular Plan.
-
Scan the QR code from your eSIM provider.
-
Label your plans (e.g., “Primary” & “Travel Data”).
-
Choose default line for calls and data.
💡 Pro Tip: I usually keep my Vietnamese SIM for calls/OTP, and activate an eSIM like Maya or Yesim for unlimited data when traveling.
Why Dual SIM Is Perfect for Travelers
When traveling internationally, using Dual SIM iPhone with eSIM is a lifesaver.
Benefits:
-
✅ Keep your main number → Receive SMS from banks, iMessage, or WhatsApp without issues.
-
✅ Buy data instantly → Download an eSIM before flying; it activates as soon as you land.
-
✅ No SIM swapping → Avoid losing tiny SIM cards at airports.
-
✅ Multiple options → Switch between providers like Pocket eSIM or Breeze eSIM.
My Personal Experience (Anna’s Note ✈️)
As someone who has traveled across Europe, Asia, and North America, I can confidently say: data reliability matters more than price.
For example, when I was in France, I used Airalo for a 5GB Europe package. It worked well, but in remote areas of Italy, Nomad had stronger roaming coverage. That’s why I often recommend keeping 2–3 eSIM apps installed — you can buy a backup in seconds if one network is weak.
Best eSIM Options for Dual SIM iPhones
Here’s a quick comparison of the top eSIM brands I’ve personally tested:
| Provider | Best For | Link |

| Maya | Easy-to-use app | Try Maya |
| Nomad | Reliable in Europe & Asia | Check Nomad |
| Yesim | Unlimited data in select countries | See Yesim |
| Ubigi | Strong in the U.S. & Japan | Use Ubigi |
