kolet has been a reliable and easy to use esim while I was travelling in Iceland. as I had hotel and bus internet access, I did add added G's to ky account and did not use kolet much, but whenever I did need it, it was quite reliable. The free 1G introductory offer w Exoticca travel was adequate for my needs.

Glad to hear Kolet felt reliable and easy while you explored Iceland. Adding extra G’s and using the free 1 G from Exoticca works well for many travelers 🌏. If you ever need a quick top‑up, the app makes it simple 🚗.

I got a 2 day free e sim in Spain, as I booked train tickets via omio. It worked immediately, let you know how much data was left and when the 2 day trial was due to end. I didn't need to buy any data as I already had data roaming on an existing home contract. However, I would definitely consider using them again, if I didn't have data where I was travelling.

Glad the 2‑day free eSIM in Spain activated instantly and showed you the remaining data. It's handy that the trial timer was clear so you knew when it would end. If you ever need extra data on the road, Kolet’s plans are ready to go 🌍✈️.

I used this eSIM during my trip to Italy and Spain, and I had a great experience. The eSIM was very easy to install, and the support team was extremely helpful whenever I had any questions. The network coverage and speed were very good, and I didn’t face any issues throughout my entire journey. Highly recommended for anyone traveling to Europe!
