Comparison of the 5 best eSIMs for traveling to Japan

Today, there are several eSIMs available for traveling in Japan. You've probably heard of Saily, Ubigi, Airalo, or Holafly. They all have offers, but when you look closely... there's always a problem:

Saily: $25 for 20 GB. Not cheap, and you have no guarantee that your favorite apps will work without crashing.

Ubigi: approximately $36 for 20 GB. They also use the Docomo network, but without control over application filtering, and the prices are very high.

Airalo: $22 for 20 GB. Cheaper than the other two, but with the same issues: some applications blocked, slow customer service, and only available in English...

Holafly: That's the last straw. Over €60 for a 30-day plan in Japan. Yes, you get unlimited data, but it's overpriced and there's no transparency about the restrictions.

👉 Result: you pay more, you get very slow support, and you may even find your apps blocked.
