Very cool, convenience in a can. A little more expensive than getting a local SIM but with the time saved finding one, not paying airport prices and having connectivity as soon as wheels hit the ground is well worth it. The crediting system works well too, finish a data plan with some data left on it, refund it to credit and purchase a different one. Perfect

Glad you found the convenience worth the extra cost over a local SIM. Saving time at the airport and getting data straight off the runway is a big win. Your description of converting leftover data into credits and buying another plan was spot on. Enjoy your travels and the instant connectivity! 🌍✈️.

Kolet made my trip super convenient! No more carrying a SIM ejector pin or waiting in line for a local SIM. Just a quick digital setup, and I was good to go. The network coverage was solid, and the pricing was better than expected. My only wish? Maybe daily unlimited data options rather than fixed data amount for 30 days, but overall, a fantastic product! Would definitely use it again! 🚀

Love how you summed it up, no SIM ejectors, no queues, just a quick setup and solid coverage. That’s exactly what we’re here for! 🚀 And we hear you on the daily unlimited data option, it’s something we’re actively working on. Hopefully, next time you travel, it’ll be even more convenient! ✨ Thanks for the feedback, and see you on your next trip!

I bought a bigger than needed package because despite their overpriced package, they give good Flying Miles deal. However, their system didn't automatically populate my flying blue number (I logged in from klm), and after purchase, they informed me that im not entitled to Miles because I didn't enter Flying Blue number manually. They credited my account with extra 1 gb, but I already have purchased oversized package coz i looked the miles... quite disappointing experience..
