First time user of Kolet and esim
It was the first time I have used the e sim function on the mobile. Air France provided a 2 day trial of Kolet whom I had never heard of before. Wonderful discovery as it made communication in Switzerland so smooth and easy. Will definitely use Kolet again.

Glad you found the setup a breeze! It's great to hear the price felt reasonable for you. Happy that the signal held up well in the UK 🌏🧭.
Kolet's Amazing Service
Kolet provided me the avenue to be able to communicate with loved ones back home which was amazing.
The only two downsides were;
1) In some places where other people had signal, mine would disappear and was missing called and messages until I came out of the shops and 2) The prices of the bundle could be made more affordable,
But apart from the above, I would give it 5*s

Thanks for sharing your experience! ✈️ It sounds like switching between available local networks helped when the signal disappeared inside shops. 📶 Our 24/7 Customer Care can reply in less than 2 minutes if you run into issues. We’ve recently lowered prices across many places, hoping it feels more affordable for you.
