Kolet becomes the exclusive connectivity partner, giving first-time users a 48-hour data boost on arrival.
Booking a package holiday just got a small connectivity bonus attached to it. Thomas Cook has partnered with French eSIM provider Kolet to hand travelers 1GB of free mobile data the moment they land, good for 48 hours of use straight off the plane.
What's New

Every package holiday booked through the online travel agency now comes with a Kolet eSIM offer attached, no upsell required. Customers get an email 72 hours before departure with a unique redemption link, and Thomas Cook is telling people to download the eSIM before they board rather than after they land, so it's already active on arrival.
Kolet becomes Thomas Cook's exclusive eSIM partner as part of the deal, which is a meaningful placement for a provider that's still building brand recognition against the likes of Airalo and Holafly.
Why It Matters
The pitch here is the first hour of a trip, not the whole vacation. Taxi apps, maps, hotel check-in messages, a text home, all of that used to mean hunting for airport WiFi or queuing at a SIM kiosk. A pre-loaded eSIM removes that friction before it starts, which is exactly the kind of small-but-visible perk that makes a package deal feel more complete without touching the price.

Key Details
- 1GB of data, usable over a 48-hour window from activation
- Delivered via a single eSIM covering more than 190 countries and multiple local networks per region
- Kolet says it already has over 750,000 travelers using its service, with 24/7 human support
- The free data is limited to first-time Kolet users, so it's a one-time sweetener rather than a repeat perk on every future booking
- Redemption link arrives by email 72 hours before travel; Thomas Cook recommends installing it before departure
Thomas Cook CMO Ryan Cotton framed it as mobile data simply being expected now, calling it “part of the holiday experience.” Kolet co-founder and CEO Eduardo Ronzano said the goal is helping “more holidaymakers stay connected overseas” as eSIM adoption keeps climbing.
Takeaway
It's a low-cost, high-visibility add-on for Thomas Cook and a solid distribution win for Kolet. Just don't expect the free gigabyte to reappear on your next booking. It's an acquisition hook, not a loyalty perk.
