Holafly Japan: honest review, hidden limits and alternative (2026)

TL;DR

Holafly offers a Japan eSIM with unlimited data, a well-made app, and a recognized brand. But looking closer, you'll find limitations rarely mentioned: an IP address routed through Singapore or Hong Kong (not Japan), a hotspot capped at ~500 MB/day, the SoftBank network (less reliable in rural areas), and a price above the competition. If you want an unlimited eSIM with a real Japanese IP, unrestricted hotspot, and the NTT Docomo network, PlanJapan Unlimited checks all the boxes.

Holafly Japan: what the service offers in 2026

Holafly is a Spanish eSIM provider that gained recognition through aggressive marketing on YouTube and social media. Their Japan offer is built on a simple argument: unlimited data, regardless of trip length.

Here's what you get with Holafly Japan:

• Unlimited data: no GB quota to monitor
• Mobile app: usage tracking, guided installation, integrated chat support
• Global coverage: Holafly covers 170+ destinations (not just Japan)
• QR code installation: standard, like most modern eSIMs
• Flexible durations: from 5 to 90 days

On paper, the offer is appealing. The Holafly app is genuinely well-designed, and the brand inspires confidence thanks to its visibility. But the offer has important nuances that sponsored reviews don't always mention.

Holafly Japan review: 5 limitations nobody tells you about

After testing and analyzing user feedback on Holafly in Japan, here are the points that deserve your attention before buying.

1. The IP address is not Japanese

This is probably the most underestimated limitation. With Holafly in Japan, your internet traffic is routed through servers in Singapore, Hong Kong, or sometimes Poland. Result: websites and apps see a foreign IP, not a Japanese one.

The practical consequences:

• Some Japanese services are inaccessible: local streaming platforms, restaurant booking apps, or certain Japanese banking services may block non-Japanese IPs
• Google Maps and search results may show results geolocated to Singapore rather than Japan
• Displayed prices on some booking sites (hotels, activities) may vary depending on the detected country
• Online payments may be refused by anti-fraud checks that detect a mismatch between your GPS position and your IP

For a traveler who simply uses Google Maps and WhatsApp, this may not be an everyday problem. But if you plan to use Japanese online services, this limitation becomes annoying.

2. Hotspot is limited to ~500 MB/day

Holafly advertises "unlimited data," but tethering (hotspot) is capped at approximately 500 MB per day. Beyond that, speed is heavily throttled or the hotspot is simply disabled.

500 MB in hotspot mode translates to roughly:

• ~30 minutes of video conferencing
• ~1 hour of web browsing
• ~20 minutes of 720p video streaming

If you're traveling as a couple and your partner doesn't have an eSIM, or if you need to connect a laptop, this limit will be reached very quickly. For more on real hotspot consumption, check our guide to eSIM hotspot in Japan.

3. SoftBank network: decent in cities, fragile elsewhere

Holafly uses the SoftBank network in Japan. It's the country's third carrier, performing well in Tokyo and Osaka but clearly behind in rural and mountainous areas:

• Uneven coverage in Tohoku, Hokkaido, and the Japanese Alps
• Unstable connection on the Shinkansen, especially on secondary lines
• Dead zones possible on islands (Okinawa, Seto) and in mountains

In comparison, NTT Docomo covers 99.9% of the Japanese population and remains the reference carrier for intercity travel and remote areas. If your itinerary goes beyond major cities — and in Japan, the most beautiful places are often in the countryside — the network choice makes a real difference.

4. Higher price than average

For a 15-day unlimited eSIM, Holafly is among the most expensive on the market. The price is partly justified by unlimited data, but you need to compare like for like:

• Other providers offer unlimited data at a lower price
• For many travelers, a 50 GB plan at a lower cost covers 2 weeks in Japan with ease
• The Holafly premium funds marketing (YouTube sponsorships, affiliates), not a better service

5. No native multilingual support

Holafly is a Spanish company with multilingual support, but most interactions are in English or Spanish. Support in other languages exists but relies on automatic translations, which can complicate resolving technical issues.

Holafly vs PlanJapan comparison: unlimited eSIM Japan

If you're deciding between Holafly and PlanJapan for an unlimited eSIM in Japan, here's a factual point-by-point comparison:

Criterion	Holafly Japan	PlanJapan Unlimited
Data	Unlimited	Unlimited
Network	SoftBank	NTT Docomo (99.9% coverage)
IP address	Singapore / Hong Kong / Poland	Japanese IP
Hotspot	~500 MB/day	Unlimited, no restrictions
Rural coverage	Decent in cities, fragile elsewhere	Excellent everywhere (Docomo)
Shinkansen	Unstable on some lines	Stable on all major lines
Multilingual support	Via auto-translation	Native (EN, FR, ES)
Mobile app	Yes (well-designed)	No (direct QR code)
Activation	QR code via app	QR code by email, 2 minutes

Summary: Holafly has the advantage of a mobile app and brand recognition. PlanJapan wins on the technical criteria that matter daily: network, Japanese IP, hotspot, and rural coverage.

Who is Holafly still a good choice for?

Let's be honest: Holafly isn't a bad product. It's a solid choice if:

• You're staying exclusively in major cities (central Tokyo, Osaka, Kyoto)
• You don't need hotspot or only very occasionally
• A Japanese IP address isn't important to you
• You like having a dedicated app to manage your eSIM
• You already use Holafly in other countries and know the service

If your trip is limited to the Tokyo-Kyoto-Osaka axis and you only use your phone for Maps and social media, Holafly will get the job done.

Why choose PlanJapan Unlimited over Holafly?

On the other hand, PlanJapan Unlimited becomes the better choice when:

• Your itinerary includes rural areas (Japanese Alps, Tohoku, Okinawa, Hokkaido)
• You plan to share your connection via hotspot with a laptop or travel partner
• You need a Japanese IP to access local services
• You travel frequently by Shinkansen and need a stable connection
• You prefer native multilingual support in case of issues
• You work remotely and need a reliable, consistent connection

The NTT Docomo network is simply the most reliable in Japan. With the PlanJapan Unlimited eSIM, you get unlimited data on this network, with hotspot included and without routing your traffic through a third country.

Holafly Japan review: what users say

Browsing travel forums, Reddit, and verified reviews, certain feedback comes up regularly from Holafly users in Japan:

Positive points mentioned

• Simple installation via the app
• Data is genuinely unlimited for on-phone usage
• Chat support is responsive for basic questions

Recurring frustrations

• "The hotspot stops working after a few minutes of use"
• "My GPS locates me in Singapore instead of Tokyo"
• "Lost connection several times on the Shinkansen to Hiroshima"
• "The price is expensive compared to other eSIMs offering the same thing"
• "The multilingual support isn't really native"

These reviews confirm the technical limitations documented above. They don't make Holafly a bad service, but they show that the "unlimited" promise needs to be nuanced.

Frequently asked questions about Holafly in Japan

Does Holafly work well in Japan?

Yes, Holafly works in Japan. Data is genuinely unlimited for direct phone use. The limitations concern hotspot (~500 MB/day), IP address (not Japanese), and rural coverage (SoftBank network).

Why is the Holafly IP not Japanese?

Holafly routes traffic through intermediate servers located in Singapore, Hong Kong, or Poland. This is a network architecture that allows offering unlimited data at a lower infrastructure cost, but it has the consequence of masking your actual location in Japan.

Does hotspot work with Holafly in Japan?

Hotspot works but is limited to approximately 500 MB per day. Beyond that, speed is reduced or tethering is disabled. If hotspot is important to you, check our comparison of eSIMs with hotspot.

Holafly or PlanJapan: which unlimited eSIM to choose for Japan?

Holafly works for basic city usage. PlanJapan Unlimited is preferable if you need the Docomo network (better coverage), unrestricted hotspot, and a Japanese IP. Check our comparison of the best Japan eSIMs for a complete overview.

Does Holafly use the Docomo network?

No. Holafly uses the SoftBank network in Japan, the country's third carrier. NTT Docomo, the network with the best coverage (99.9%), is used by other providers like PlanJapan.

Is Holafly available in multiple languages?

The Holafly app and website are partially translated into multiple languages. Customer support operates primarily in English and Spanish, with responses in other languages via auto-translation.

Our recommendation

Holafly is a serious provider with a good app and a genuine unlimited data offer. If you're looking for a simple solution to stay connected in Tokyo and Osaka, it's a choice that works.

But if you want an unlimited eSIM without compromises for Japan — Docomo network, Japanese IP, hotspot included, coverage even in the most remote villages — the PlanJapan Unlimited eSIM is the alternative we recommend.

Because in Japan, the most memorable moments aren't always in big cities. And when you're in Shirakawa-go, atop Mount Koya, or on a beach in Okinawa, you want to be able to count on your connection.
