The Ultimate Guide: How to Install and Activate Your eSIM on iPhone & Android

Are you getting ready for your next adventure? Whether you’re heading to the busy streets of Tokyo, the beaches of Bali, or a business meeting in New York, staying connected shouldn’t be a struggle.

At simpleSIM, based in the heart of Paris, we provide travelers with reliable, affordable, and high-speed eSIMs worldwide. We offer everything from unlimited data to plans with voice and SMS, ensuring you have the perfect fit for your journey.

If this is your first time using an eSIM, don’t worry! It’s much simpler than handling a physical SIM card. Follow this step-by-step guide to get connected in minutes.

1. Before You Begin: Pre-Installation Checklist

To ensure a smooth setup, please check these four essential points:

  1. Check Device Compatibility: Not all smartphones support eSIM technology yet. The easiest way to be sure is to use our Compatibility Checker. If your model is listed there, you’re all set!
  2. Ensure your phone is carrier-unlocked: Your device must be “SIM-free” or unlocked to accept an eSIM from a provider other than your current home carrier.
  3. Connect to Wi-Fi: You will need a stable internet connection to download and register your eSIM profile on your phone’s hardware.
  4. Have your simpleSIM QR Code ready: You should have received your unique QR code via email immediately after your purchase on simplesim.fr.

Pro Tip: We recommend installing your eSIM the day before you travel or at the airport before departure so you have data the moment you land!

Once you land at your destination, there are two final clicks to get your data running:
