Two days’ eSIM data on arrival
Transavia France has partnered with Kolet, a French start-up specialising in eSIM, to build a mobile connectivity solution into the customer journey. Passengers receive two days of mobile internet abroad, up to 1GB, free on arrival, and can then top up via the Kolet app. With the offer, Transavia aims to support digital habits the moment travellers land. The set-up is rolling out across Transavia France’s network, part of the Air France-KLM group, and simplifies access to data without swapping SIM cards. Kolet covers more than 190 destinations and says activation takes only a few minutes.
After installing the eSIM on a compatible smartphone, travellers activate their plan in minutes while keeping their primary number. They can then use up to 1GB of data over the first two days of their stay. Subsequent top-ups are purchased in the Kolet app, with the option to pay in Flying Blue Miles or to earn 10 Miles per euro spent.
Normalising eSIM in international travel
For the airline, connectivity has become an immediate need on arrival: checking directions, accessing bookings, letting friends and family know you’ve landed. The programme also aims to address travel stress, with 90% of air passengers reporting some level of anxiety during their journey, according to a 2025 Amadeus study. Transavia presents the partnership as a way to enrich the customer experience with useful, integrated services that can be activated without friction. “We are constantly looking to enhance our passengers’ experience with simple, useful services,” said Julien Mallard, deputy managing director, commercial, at Transavia France. “Mobile connectivity is now part and parcel of travel, and this partnership with Kolet allows us to meet that need smoothly and immediately.”
For Kolet, the deal strengthens a B2B2C strategy of distributing its service via travel brands to make eSIM a standard for international use. For the French start-up, it follows partnerships with Philippine Airlines and Axa, used to demonstrate a proposition aimed at removing unexpected roaming fees with local plans while keeping the primary line active. “Data has become an essential part of travel,” said Eduardo Ronzano, chief executive of Kolet. “This is no longer just about comfort but an immediate need on arrival. With Transavia, we want to make this connectivity visible and accessible at the right moment in the journey.”
Founded in 2024, Kolet offers a fully digital app available in more than 190 countries and holds B Corp certification. Transavia, the low-cost carrier in the Air France-KLM group, operates nearly 400 routes from France, the Netherlands and Belgium to Europe and the Mediterranean. According to the partners, the rollout begins in May 2026 with integration across key customer touchpoints.
