Coverage, networks and speeds in Japan
Japan eSIMs connect to SoftBank, KDDI and NTT Docomo depending on plan. Japan is consistently among the top five searched eSIM destinations worldwide.
5G in Tokyo, Osaka, Kyoto and along the Shinkansen corridor; typical 50 to 200 Mbps. 4G coverage is excellent in rural areas and mountains, including Mount Fuji trails in season.
Networks used by the Japan eSIM
Speed figures are typical ranges reported by the networks and independent testing in 2026. We publish our own field speed tests for each destination after launch and update this page monthly.
How to install and activate your Japan eSIM
Buy the plan
Pick a Japan plan, pay by UPI, card, Apple Pay, Google Pay or PayPal. The QR code arrives by email and in the app within 60 seconds.
Install on Wi-Fi before you fly
On iPhone: Settings, Cellular, Add eSIM, scan the QR. On Android: Settings, Network, SIMs, Add eSIM. Takes about two minutes. Nothing is used until you land.
Land and switch it on
Turn on the Universal eSIM line and data roaming for that line only. It connects to a Japan network automatically and your validity starts now, not at purchase.
Keep your home number
Leave your Indian SIM active for calls and OTPs with data roaming off. WhatsApp keeps working on your usual number.

Japan travel connectivity tips
- Register on Visit Japan Web before departure for faster immigration and customs QR codes.
- Add a Suica card to Apple Wallet or Google Wallet before you travel; it needs data to top up with a foreign card.
- Japan is data-heavy for tourists: translation, transit routing and photos. Choose 10GB for a two-week trip.
- Cash is still common in small restaurants; data lets you find the nearest 7-Eleven ATM.
- Local numbers are hard for visitors to get and rarely needed; a data-only eSIM is the standard choice in Japan.
Airports with coverage on arrival
- Narita (NRT)
- Haneda (HND)
- Kansai (KIX)
- Chubu (NGO)
- New Chitose (CTS)
Apps you will want data for
- Google Maps (transit is excellent)
- Suica or PASMO in Apple Wallet
- Japan Travel by Navitime
- Visit Japan Web
- Google Translate camera mode
Japan eSIM vs roaming vs local SIM vs other providers
How a Universal eSIMs 5GB plan compares with the alternatives most travellers consider. Competitor figures are list prices observed on 25 October 2026 and change often.

When to choose a regional or global plan instead
If Japan is one stop on a longer trip, the Asia eSIM covers 22 countries on one QR code and usually costs less than two single-country plans. For trips across three or more regions, the Global eSIM covers 130+ countries. Peak demand: late March to early April (cherry blossom), October to November (autumn colours).

Japan eSIM: questions travellers ask
Does the Japan eSIM allow hotspot and tethering?
Yes. Every Universal eSIMs plan, including all Japan plans, allows hotspot and tethering at no extra charge and with no separate cap beyond the plan's data. Unlimited plans run at full speed for the first 2GB each day and at 3 Mbps after that, which still handles maps, messaging and music.
Which networks does the Japan eSIM use?
The Japan eSIM connects to SoftBank, KDDI au and NTT Docomo. Your phone picks the strongest signal automatically. 5G is included where the network offers it and your phone supports it.
When does the validity start?
Validity starts when the eSIM first connects to a network in Japan, not when you buy or install it. You can buy weeks ahead, install at home on Wi-Fi, and nothing is consumed until you land.
Can I make calls with the Japan eSIM?
The plans on this page are data-only. Calls over WhatsApp, FaceTime, Telegram and similar apps work over data. Keep your home SIM active with data roaming off to receive regular calls and OTPs on your usual number.
Which phones work with the Japan eSIM?
Any carrier-unlocked phone with eSIM support: iPhone XS, XR and newer; Samsung Galaxy S20 and newer, Z Fold and Flip series, A54 and A55; Google Pixel 3 and newer; and many OnePlus, Motorola, Xiaomi and Oppo models. Check your exact model before buying. If your phone does not support eSIM, order a physical travel SIM instead.
How much data do I need for Japan?
Most travellers use 300MB to 700MB a day for maps, messaging, social media and a few video calls. A 5GB plan covers a one-week trip; a 10GB plan covers two weeks; heavy video uploaders and anyone sharing a hotspot should pick 20GB or Unlimited. Use the data calculator for a personal estimate.
Can I top up the Japan eSIM without reinstalling?
Yes. Buy a top-up from your account or the app and it is added to the same eSIM within a minute. You never need a second QR code for the same destination.
Is a Japan eSIM cheaper than international roaming from India?
Yes, usually by 60 to 90 percent. Indian operators' international roaming packs for Japan cost roughly ₹575 to ₹1,101 per day for 0.5 to 1GB, or ₹2,999 to ₹5,999 for 10 to 30 days with 5 to 15GB. Our Japan 5GB 30-day plan costs ₹799. See the Japan eSIM from India page for the full comparison.
What is the refund policy?
If the eSIM cannot be installed on a compatible, unlocked phone, we refund in full. Unused and uninstalled plans can be refunded within 30 days of purchase. Once an eSIM has connected to a network, the plan is considered used. Full terms are in the refund policy.
Can I use the eSIM on two devices or share it?
An eSIM profile installs on one device at a time. To connect a second device, use the hotspot, which is allowed on all plans, or buy a second eSIM for that device.
