Flex guide
eSIM Installation made easy
Install before you fly, then turn on Data Roaming when you're heading to the airport or once you land. Flex sends the QR instantly, so you can stash it on your phone at home.
Before you start
- Open the Flex QR email on a laptop or spare phone so your travel phone can scan it.
- Stay on Wi-Fi. The download takes seconds when you're on a solid connection.
- The QR code works once, so install calmly at home.
- Don't delete the Flex eSIM after install - removing it means buying another QR.
- Turn Data Roaming on the day you fly or right after landing. Keep it off at home so your main SIM keeps serving calls.
Three quick checks
Do these first. Everything else becomes autopilot after that.
Open the Flex email
Use a laptop or spare phone to open the "Flex eSIM ready" email so the QR code is ready to scan.
Add eSIM in Settings
On your travel phone, go to Settings > Mobile/Network and tap Add eSIM (or Add Data Plan).
Scan and wait
Scan the QR, follow the prompts, and rename the plan "Flex" so you can spot it quickly later.
Choose your phone
Each tab keeps the steps simple. Swap the toggle to match your device.

Turn on Data Roaming the day you fly
