I was initially worried because I couldn't connect at all due to problems with the setup, but I was able to set it up by asking for help on ChatGPT! Make sure to do it under airport Wi-Fi conditions and confirm that it connects properly even after turning off Wi-Fi before proceeding. It worked without any problems in four European countries.

It offers incredible value for money. It worked perfectly at Turkish airport, which was very helpful for getting around the airport. I also used it with the AI-powered mobile phones without any problems, and it was a fun experience to navigate the airport and ask the AI ​​for advice on souvenirs. In Barcelona, ​​there were some areas with poor signal reception, but it still worked without any issues. One point of concern is that the manual setup instructions need to be easy enough for even a novice to understand. I applied for two lines, and one activated automatically without any problems, but the other took a long time to activate, wasting a day. It seems the reason was that it misidentified an e-SIM I had used in the past, causing the APN settings to become incorrect. After manually setting the APN, it worked without any problems from the second day onwards.

The connection was excellent throughout the entire trip. I visited Belgrade in Serbia and Tivat, Kotor, and Budva in Montenegro. I always had high-speed internet everywhere, without any issues.

Very easy to use, only few clicks for installing. I love this concept for its wallet's friendly also plenty of data while you were travelling. Highly recommend, even though at the beginning might seem difficult to understand how to install, but once you get through everything seems very straightforward.

The SIM card connected quickly. The signal was strong everywhere. Sometimes the connection became unstable in large buildings and between towns, but I think that's normal. The ability to make calls and send/receive text messages was useful.
