Buy and install before departure

The safest workflow is to buy before departure and install on stable Wi-Fi. This leaves time to solve device, email, QR code, or setup issues before your flight.

Activate mobile data after arrival

After arriving in the covered destination, select Skylano eSIM for mobile data and enable data roaming according to the plan instructions. Make sure your phone is not using your home carrier's roaming data.

Understand plan validity

Validity rules vary. Many travel eSIM plans start after first connecting to a supported local network, while some may start after installation. Always follow the product page and order instructions.

  • Confirm device compatibility
  • Save order number and QR code
  • Do not delete after installation
  • Select eSIM for mobile data after arrival
  • Enable data roaming if required
