Happy to hear the app works so smoothly for you. Switching between countries and topping up on the go really should be effortless. You can convert leftover data into credits whenever you need; it’s all right inside the app 🤝🌏.

It’s great to hear you consider it one of your favorites. Enjoy staying connected wherever you roam 🌍📱.
It is very convenient
It is very convenient. I started with flying blue members two day 1G data for free and then switched country and bought 3G which worked out. The leftover can be returned as credit to be used in the next country! Wow. Speed is 5G.

Glad you found the app super convenient and the 5G speed impressive! 🚀 It’s great that the free 1 GB for Flying Blue members got you started smoothly. When you have leftover data, just open the Kolet app, locate the plan and tap the three dots (⋯) to convert it into credits for your next trip. Enjoy the seamless switch to 3 GB in the new country and happy travels! 💛

We’re happy you found the plan reasonable and the service excellent. It’s awesome you’ll keep Kolet for your next adventure 🌍✈️. Safe travels.
Glad I could sort it out beforehand
It was easy to use, it worked really well in a country where most e-sim providers don't go, and what I didn't use, I could keep as credit for my next trip. This is great! The only small problem was that it switched to Kolet at my in-between stop in Europe where my normal sim still works, this caused a bit of a problem as I was temporarily out of reach.

Glad to hear the app was easy to set up and performed well where other e‑sim options fall short. If you still have unused data, you can turn it into credits right now by opening the app, locating the plan and tapping the three dots (⋯). Switching to Kolet at your European stop can momentarily drop the signal, so manually picking the local network often helps, and our 24/7 Customer Care usually replies within two minutes. Safe travels and enjoy the next adventure! 🌍📶

So far so good my last trip was Guadeloupe 🇬🇵 and it work really good when there’s signal. But some zone it doesn’t work but overall I give it a⭐️ ⭐️⭐️⭐️ start. Now going to Dominican Republic 🇩🇴 I’m gonna try it

Glad it kept you online in Guadeloupe! If you run into a spot with no signal, manually switching to another local network often improves connectivity, and our 24/7 Customer Care can reply in under 2 minutes. Have a great time in the Dominican Republic, let us know how it goes! 🌐🏖

This is the first time I have used an ESIM but was very impressed, I had a free trial for two days with Kolet, it was very good, really easy to set up and I would use again next time I go abroad.
