What do I need to install an eSIM for Caribbean travel?

You need an eSIM-compatible, carrier-unlocked smartphone, a stable internet connection (Wi‑Fi is best) to download the eSIM profile, and your EasyAlo confirmation email with the QR code or activation details. It’s also helpful to have a second device, such as a laptop or tablet, to display the QR code while your phone scans it. Once installed, you just enable data roaming for the eSIM and set it as your preferred line for mobile data before your flight.
