How to Activate an eSIM on iPhone

If you’re using an iPhone, setting up an eSIM is quick and straightforward. Apple has made it really simple to manage multiple numbers and data plans on one device. In this guide, we’ll explain what Dual SIM technology is, how it works on iPhones, and how you can activate an eSIM step by step.

What Is Dual SIM on iPhone?

Dual SIM allows your iPhone to use more than one mobile plan at the same time. This means you can:

  • Keep one line for personal calls and another for work
  • Add a local eSIM data plan while traveling without removing your home SIM
  • Switch between carriers easily without swapping physical SIM cards

On iPhones, Dual SIM on older models usually means one physical SIM + one eSIM (with multiple eSIM profiles stored but only one active), while newer models allow two eSIMs to be active at the same time without needing a physical SIM.

Which iPhones Support eSIM?

Apple first introduced eSIM with the iPhone XR/XS, and every iPhone since then supports it.

Here’s how to check if your iPhone supports eSIM:

  • Open Settings
  • Tap Cellular
  • Look for Add eSIM

If you see the option, your device is eSIM-ready.

⚠️ Remember: Your iPhone must be unlocked to use eSIM plans from other carriers.

How to Activate an eSIM on iPhone

After purchasing a data plan from Travely eSIM, you’ll receive setup instructions right inside the app.

  • Open Travely app

    1. Direct Installation (Recommended): Tap Install eSIM
    2. QR Code Installation
      • Open Settings > Cellular > Add eSIM
      • Scan the QR code you received
    3. Manual Installation
      • Open Settings > Cellular > Add eSIM
      • Type in the activation details (provided in the App)
  • Follow the on-screen setup guide and wait for activation.
  • Label your plan (e.g. “Travely Spain”)

Then, to access data when you arrive at your destination:

  • Go to Settings > Cellular
  • Make sure your Travely eSIM line is ON
  • Enable Data Roaming if required (check Travely app installation instructions)
