"Bought my Japan eSIM 10 minutes before landing. Scanned the QR, had data before I even left the plane. Unreal."

An eSIM is a digital SIM built into your phone. Instead of a physical card, you download a profile by scanning a QR code. It connects you to a local network in your destination country, giving you data without swapping SIMs or paying roaming fees.
Most phones from 2018 onward support eSIM, including iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later, and many more. Check our Compatibility page for the full list before you buy.
Instantly. As soon as your payment is confirmed, your eSIM QR code is emailed to you — usually within seconds. You can activate it the moment you land.
Yes. Most eSIM-capable phones support dual SIM, so you can keep your home number active while using your MesaeSIM eSIM for data abroad.
