There were three of us traveling, and I took three SIM cards. It was convenient, and everything worked flawlessly in all the cities we visited. Customer support responded quickly and resolved the issue.

Whenever I ran into an issue, the response was quick and helpful. However, the service wasn’t always easy to use, as the connection was sometimes unreliable.

Had this sim in my trip in Italy and Greece. It worked in the places where even Italian operators didn't had a signal. In the opened sea I was the only person who had a line. Highly recommended

We bought an eSIM for a three-week trip to the Seychelles. It worked 100%, never let us down. It also worked perfectly on the islands of La Digue and Praslin. It was easy to install, turned on upon arrival, and started working right away. Very convenient and great value. Physical SIM cards are very expensive in Mahe. I used it all day, checking Instagram, posting stories, and we didn't use up all the data in three weeks. We only used Wi-Fi in the evenings. So, I recommend it to everyone! Very easy, fast, convenient, and super affordable!

In Europe, eSIM with a mobile number and call functionality is the cheapest option. You can connect immediately at Budapest airport, but in hotels in Budapest, Zagreb, and Ljubljana, the internet speed is either very slow or impossible to connect at all. Outdoors and in the suburbs, there are generally no problems. I haven't used the call functionality, so I'm not sure. If the hotel offers free Wi-Fi, it's a cost-effective choice.

I flew to Indonesia via Uzbekistan and India. Everything worked perfectly everywhere. I activated it in Russia a couple of days before departure, and about 10-15 minutes after landing in all three countries, the internet was back on. I recommend it.
