eSIM on the e-ticket, from the checkout to the border
Match the line to one plan, sell it in your ticket checkout, and put the install step in the e-ticket.
Short answer: A ticket already knows the line, the date, and the countries on the route. The eSIM API turns that into one plan in your checkout, an order when the payment clears, and an install step in the e-ticket.

- One plan for the line
- Paid with the ticket
- Installed before departure
The line sets the plan. The e-ticket carries the install.
How the eSIM API runs in a ticket checkout: the line, the checkout, the e-ticket, and the trip. Pick a step to see it.
Match the line to a plan
The line holds the countries in route order. One regional plan covers a line across a border, and a local plan covers one country.
- Trigger
- Passenger picks a line
- Measure
- Cross-border tickets with a matched plan
Offer it in the checkout
The plan sits next to the seat and the bag in your ticket checkout, at your price. The order goes to the API when the payment clears.
- Trigger
- Ticket in the basket
- Measure
- Orders per 100 plans shown
Install step in the e-ticket
The e-ticket email holds the install step. The passenger installs on Wi-Fi before departure, because the signal can drop at the border.
- Trigger
- E-ticket sent
- Measure
- Installs before departure
Help on the trip
If the data stops after the border, the help message points to data roaming for the eSIM line and the install steps.
- Trigger
- Passenger asks for help
- Measure
- Help requests per 100 orders

Before you choose
Short answers to the common questions. The partner agreement sets the final terms.
What if the data stops at the border?
The passenger checks that data roaming is on for the eSIM line. The install steps in the e-ticket email show how.
Can we keep our checkout?
Yes. Show the plan in your checkout and create the order through the API. The passenger stays in your flow.
Can a ticket platform sell the same plan?
Ticket platforms that resell your seats join through the OTA setup.
What about passengers who buy at the station?
Keep SIM packs at the ticket desk for walk-up passengers. Staff check the phone first.
