What Is Dual SIM Card on iPhone?
Hi, I’m Anna – a travel enthusiast who has tested more than 15 eSIM providers during my trips across Europe, Asia, and the US. If you own an iPhone, you’ve probably heard about the dual SIM card on iPhone feature. But what does it mean, and why is it such a game-changer for frequent travelers like me?
Put simply, dual SIM on iPhone allows you to use two SIMs at the same time – either 1 nano SIM + 1 eSIM (on iPhone XS/XR and newer) or even dual eSIMs simultaneously (on iPhone 13 and later). This means you can keep your primary number for calls, OTPs, and banking, while using a travel eSIM for affordable data abroad.

How Dual SIM Works on iPhone
Compatible iPhone Models
Not every iPhone supports dual SIM. Here’s a quick breakdown:
-
iPhone XS, XS Max, XR → 1 nano SIM + 1 eSIM
-
iPhone 11, 12 → same setup: 1 nano SIM + 1 eSIM
-
iPhone 13, 14, 15 → support dual eSIM (2 eSIMs active at once)
-
iPhone 14 (US models) → eSIM-only, no physical SIM tray
💡 If you’re using an older iPhone, you won’t get dual SIM capability.
Setting Up Dual SIM on iPhone

Go to Settings > Cellular > Add eSIM.

Scan the QR code or enter details from your eSIM provider.
-

I keep my local Vietnamese SIM active to receive OTPs.
