What You Need Before Installing Your eSIM
- Your eSIM QR code — sent to your email. Retrieve it at cryptoesim.io/order-lookup if lost.
- A second device to display the QR — display on a laptop or tablet so you can scan with your phone.
- Strong WiFi — the eSIM profile must download over internet.
- A carrier-unlocked phone — locked phones cannot install travel eSIMs.
