Great experience using the Kolet app to download and activate a free eSIM
We had a free data plan of up to 2 GB for 2 days provided by Kolet. It was very easy to download the eSIM and activate it on arrival in Hawaii. The app is very useful-friendly.

I’m not very trusting and not usually impressed but Kolet gave me seamless data in America. Absolutely fantastic. I saw them on the virgin Atlantic app and took advantage of their 2 days with the flight and then another 15 days.

Wow, that's great to hear! Your seamless data experience across the 2-day flight and the following 15-day stay in America sounds fantastic. Thanks for giving Kolet a chance, we're thrilled you enjoyed it 🌍📱.
