Frequently asked questions — Japan eSIM
Everything you need to know before you go. Another question? Our support answers 24/7.
See the full FAQWill the eSIM work on the Shinkansen (bullet train)?+
Yes, our eSIM connects to NTT Docomo and KDDI networks which provide reliable coverage along all Shinkansen routes, including tunnels. You will have uninterrupted data for maps, streaming, and messaging throughout your journey between Tokyo, Osaka, Kyoto, Hiroshima, and Hakata.
Can I use the eSIM to navigate Tokyo Metro and subway systems?+
Absolutely. Our partner networks cover all Tokyo Metro, Toei Subway, and JR lines underground. You can use Google Maps or Japan Travel apps to navigate subway stations in real time. Some deep platforms and older tunnel sections may have brief interruptions.
Is the eSIM cheaper than renting a portable WiFi at the airport?+
Significantly. Portable WiFi rental costs $5–$12 per day plus a deposit, requires pickup/return at the airport, and needs daily recharging. Our Japan eSIM costs from $4.90 for the entire trip, works immediately on landing, and requires no pickup line, no deposit, and no charging.
Does the eSIM work at Mount Fuji and national parks?+
Coverage extends to the base of Mount Fuji (Fujisan Station area), Hakone, Nikko, and most major national parks. At the summit of Mount Fuji and deep rural trails, coverage becomes sporadic. We recommend downloading offline maps before heading to remote areas.
Can I use it with Google Maps and Japan Travel apps?+
Yes, Google Maps, Japan Travel, Navitime, Hyperdia, and all major travel apps work perfectly. The eSIM provides high-speed data for real-time navigation, train schedule lookups, and restaurant recommendations throughout Japan.
What operators does the Japan eSIM use?+
Our Japan eSIM connects to NTT Docomo, SoftBank and KDDI (au) — Japan's three largest networks. You get 5G on KDDI and SoftBank in major cities, with 4G/LTE fallback via NTT Docomo across 99% of populated areas, including all airports and train stations.
Does the Japan eSIM support 5G?+
Yes — our Japan eSIM supports 5G on KDDI (au) and SoftBank networks, with 4G/LTE fallback on NTT Docomo. 5G is available in Tokyo, Osaka, Yokohama and Nagoya. Japan's 4G networks are among the fastest in the world, so even without 5G you get excellent speeds for streaming, maps and video calls.
Does the Japan eSIM work in Tokyo?+
Yes — Tokyo has excellent 5G coverage from KDDI and SoftBank in central districts (Shibuya, Shinjuku, Ginza, Roppongi). NTT Docomo provides reliable 4G/LTE fallback across the Greater Tokyo area. All major stations (Tokyo, Shinagawa, Ueno) and airports (Narita, Haneda) are fully covered.
How fast is the Japan eSIM in major cities?+
In Tokyo, Osaka and other major cities, 5G speeds typically reach 200–800 Mbps on KDDI and SoftBank networks. In areas without 5G, 4G/LTE delivers 50–200 Mbps — more than enough for streaming, video calls and navigation.
Can I use my Japanese IC card (Suica/Pasmo) with the eSIM?+
Yes. Digital Suica/Pasmo on iPhone and Android work independently of your data connection. You can add and recharge IC cards using your TravelNet data connection, making it seamless to use one phone for both transit and internet.
Do I need a VPN for Japan?+
No. Unlike China, Japan has no internet restrictions. All websites, apps, and streaming services (Netflix, YouTube, Spotify) are fully accessible. A VPN is optional and works with our eSIM if you prefer one for public WiFi hotspots.
What if my phone is a Japanese model purchased in Japan?+
Most Japanese-market phones sold since 2021 (SIM-free models) support eSIM. Some carrier-locked phones from Docomo, au, or SoftBank may have restrictions. Check if "Add eSIM" appears in Settings > Cellular. SIM-free iPhones and recent Google Pixel and Samsung models work without issues.
Can I make phone calls with the Japan eSIM?+
Our eSIM is data-only, so direct cellular calls are not supported. Use WhatsApp, FaceTime, Skype, or LINE for voice and video calls over data. Most cafes, hotels, and restaurants in Japan offer free WiFi for backup.
Does the eSIM work in Okinawa and remote islands?+
Yes, our partner networks cover Okinawa's main island, Naha, and popular islands like Ishigaki and Miyako. Coverage on very remote or uninhabited islands may be limited, but all major tourist destinations are well covered.
How much data do I need for a 2-week Japan trip?+
For maps, social media, messaging, and occasional video calls: 5 GB is sufficient for light users, 10 GB for moderate users. For streaming, frequent navigation, and social media sharing: 20 GB or unlimited recommended. Most travelers find 10 GB comfortable for two weeks.
Can I use LINE with the Japan eSIM?+
Absolutely. LINE works flawlessly over our data connection. Keep your LINE account active with your usual number while using TravelNet data for messaging, calls, and stickers. This is especially convenient since LINE is the primary messaging app used by Japanese services.
Is the eSIM compatible with JR Pass and SmartEX apps?+
Yes. All JR-related apps including SmartEX (for booking Shinkansen tickets), JR West, and JR East apps work with our eSIM data connection. You can book, modify, and display train tickets directly from your phone without needing station WiFi.

Why use an eSIM in Japan?
Using an eSIM during your trip to Japan fundamentally changes your connectivity experience. The first reason is financial: roaming charged by traditional carriers can reach several dollars per megabyte, making your bill explode after just a few days in Japan. With the TravelNet eSIM, you pay a fixed, transparent price known in advance, with no nasty surprises when you get home.
The second advantage is avoiding the hassle of a physical SIM card at the airport. On arrival in Japan, there's no need to find a kiosk, stand in line, show ID, or fill out forms. Your eSIM is already installed on your phone: you land connected. That's a precious time-saver, especially after a long flight.
Instant activation is the third benefit. A few minutes after your purchase, you receive your QR code by email. You install it calmly on Wi-Fi before departure, and the data line activates automatically as soon as you pick up a local network in Japan. No technical know-how is required: the eSIM sets up in under 2 minutes.
Keeping WhatsApp and your number is essential for many travelers. The TravelNet eSIM provides data only: your usual number stays active, and WhatsApp, FaceTime, iMessage, or Telegram keep working normally. Your loved ones reach you as usual, and you keep your groups, contacts, and history without changing anything.
Finally, everyday convenience makes all the difference in Japan. A reliable connection lets you use Google Maps to navigate Osaka, book a taxi or restaurant, translate a menu in real time, share your photos, and stay productive if you work remotely. The eSIM turns your smartphone into a self-sufficient travel companion, from takeoff to your return.
In short, the Japan eSIM combines savings, simplicity, and peace of mind. It's the preferred solution for modern travelers and digital nomads who don't want to pay for roaming, waste time with a local SIM card, or risk being disconnected on arrival.
