This great esim is better than using services like Mobimatter, Yesim, and others. The internet speed is faster, the connection quality is better, and the price is absolutely fantastic! I'll be using it all the time now! Highly recommended!

Properly recommended to the sane to not run behind airport or hunt for Esim in the city and get one just as you land in a new city.

It worked perfectly for Croatia and Montenegro, 10/10. At first, it was hard to get a signal when crossing the border, but the rest was perfect.

This 5G roaming service is truly amazing! Whether navigating bustling cities or visiting remote towns, the signal remains consistently strong and extremely stable. Even in crowded transportation hubs, the network speed is smooth and uninterrupted, and video calls are crystal clear, almost face-to-face, with absolutely no noticeable delay. Having a French SIM card allows you to apply for local apps and make calls, which is quite convenient. I used about 1GB of data per day, which was clearly too much this time. The most convenient thing is that upon arrival at my destination, there's no need to change my SIM card; the system automatically connects to the internet instantly. The ultra-wide bandwidth allows me to enjoy the same lightning-fast experience as when handling business or sharing high-definition travel videos. This high-quality network experience, "cross-border and zero-time zone," is undoubtedly the best choice for modern travelers, completely eliminating the anxiety of intermittent network connections when traveling abroad.

The SIM card worked perfectly both in the Canary Islands and in Paris — the connection quality was always excellent!
