Trustpilot4.8Excellent
  • Japan eSIM activated at Narita in 2 minutes

    Activated at Narita airport in less than 2 minutes via QR code, without any complicated setup and without having to hunt for a SIM card shop on-site. The 4G connection on the NTT Docomo network established itself automatically. Throughout the entire stay in Tokyo (Shinjuku, Shibuya, Akihabara), the connection never dropped, even in underground passages. Way better than my previous Holafly Japan eSIM, which took half an hour to activate.

    Tom75019
  • cheapest Japan eSIM, all apps work

    I got a voilà eSIM for Japan because it was the cheapest option I found when comparing it with Airalo, Holafly, and Ubigi. The result: great network coverage everywhere (4G NTT Docomo), all my apps worked perfectly—Google Maps, TikTok, banking apps, nothing was blocked. Connection without roaming fees, instant activation. I highly recommend voilà for trips to Japan.

  • Best Japan eSIM for a Tokyo, Kyoto, Osaka itinerary

    Used for 15 days on a classic Tokyo, Kyoto, Osaka circuit. The 10 GB data plan was more than enough for heavy use (constant Google Maps, Instagram photos, WhatsApp calls). The NTT Docomo network remained excellent throughout the entire Shinkansen journey. I compared Japan eSIM prices before leaving: voilà was about 8 euros cheaper than an Airalo Japan eSIM for an equivalent plan, plus it had French-speaking customer service.

    Manon Lefèvre
  • 1 month in Japan with voilà, no bugs, no blocked apps

    Using the app for an eSIM in Japan for a full month. The ideal solution if you don't want to break the bank with other competitors: the Japan eSIM prices are unbeatable. I chose the 50 GB option for extra peace of mind, which was more than enough despite heavy use (GPS with Google Maps everywhere, social media, streaming), and I almost never needed the hotel WiFi. No bugs, no blocked apps, and the 4G connection on the NTT Docomo network remained reliable from the first to the last day, from Tokyo to Kyoto and through Nara. Customer service is top-notch and super responsive on WhatsApp. Much better than a Saily Japan eSIM or a physical SIM card bought locally.

    Bintou Soumare
  • Top-tier eSIM in Japan, unbeatable prices, responsive customer support

    eSIM tested and approved in Japan, at an unbeatable price. Ultra-fast connection right after landing at Haneda, stable 4G network throughout the whole trip from Tokyo to Osaka to Hiroshima. Very responsive customer service in case of any issues (WhatsApp support, replies in minutes). I compared it with a Saily Japan eSIM and an Airalo Japan eSIM before buying: voilà was cheaper for an equivalent data plan, with no hidden fees. The price shown is the final price, no bad surprises. I highly recommend it.

  • voilà eSIM perfect for a romantic trip to Japan

    Ten days between Kyoto, Nara, and Hakone. We were looking for an affordable Japan eSIM without sacrificing network quality. voilà offered the best value for money among the Japan eSIM plans we compared (Holafly, Airalo, Ubigi). Stable 4G connection everywhere, including in the rural areas around Mount Fuji. Translation apps and Google Maps worked without interruption from the first to the last day. Instant activation, zero roaming fees. We recommend it to all travelers.

    Inès Berthier
  • Budget-friendly Japan eSIM for a 3-week road trip

    Three weeks of road-tripping through Japan (Tokyo, Hiroshima, Fukuoka, Sapporo) with a 20 GB voilà eSIM plan. Network coverage via KDDI and NTT Docomo depending on the area, always reliable even outside the big cities. The price was clearly lower than Saily Japan or Holafly Japan eSIMs for the same amount of data. Only small downside: you have to remember to activate the eSIM yourself upon arrival, but the tutorial in the voilà app is very clear. I'll definitely use voilà again for my next trip to Asia.

    Kevin.R29
  • reliable Japan eSIM, excellent value for money

    I stumbled upon voilà when I was looking for the best eSIM for Japan before my vacation. I got their eSIM and honestly, I was extremely satisfied. Since I was looking for an eSIM with good value for money and reliability in Japan, I definitely wasn't disappointed. Immediate connection upon arrival at Narita airport, solid network throughout the whole trip, and prices well below what Holafly or Airalo offer for an equivalent Japan eSIM plan. I can only recommend voilà for staying connected while traveling in Japan.

  • Reliable Japan eSIM for remote work, 30 GB in 30 days

    One month of remote work in Tokyo, 30 GB used without going over. voilà 5G is available in major Japanese cities (Tokyo, Osaka, Nagoya) and the network coverage is excellent, even in cafes and coworking spaces. Data sharing is included, which is super handy for working on a laptop. Zero blocked apps: ChatGPT, banking apps, SaaS tools—everything worked perfectly. No reason to go with Airalo or Saily for Japan.

  • Best eSIM for Japan, 3 weeks in Tokyo, Kyoto, Osaka and Okinawa

    I didn't know about voilà eSIM until a Japanese friend told me about it. He said it was the most reliable solution he uses daily in Tokyo. My wife and I went to Japan for 3 weeks (Tokyo, Kyoto, Osaka, and Okinawa) and we each got 50 GB. The network is ultra-stable and fast, even in the Tokyo subway on the Yamanote line, or in more remote areas like Mount Fuji or Hakone. It's clearly the best network coverage we've tested in Japan, on the NTT Docomo network. I had previously used a Holafly Japan eSIM, an Airalo Japan eSIM, and Ubigi, and I always had connection issues or blocked apps. These brands block TikTok and banking apps for no reason. With voilà, none of that happens. All apps work normally: Google Maps, Uber, banking apps, everything. voilà is clearly the cheapest Japan eSIM for this level of network quality. Plus, you can easily top up from the app if needed.
