This is my first time using Esim while traveling. I was really worried about connecting when I arrived. And lo and behold! It activated instantly. Just need to enable roaming. Installation was very simple. Everything is easy to use. Excellent connection, speed, signal everywhere. I definitely recommend it!

I don't usually leave reviews but the response I get from the live chat when I had trouble was too impressive I had to find the review button to drop this review. Problem solved within minutes of chatting. Unbelievably good after sales service. Highly recommended.

It's a great deal, especially compared to buying a SIM card in Europe. The internet was out for an hour once, but otherwise, no complaints.
