Japan Mobile Network & Performance

01

Mobile Networks

Japan offers one of the most advanced mobile networks in the world, with strong nationwide coverage and high-speed data across cities and travel destinations.

The three main network operators in Japan are:

  • NTT Docomo – Widest nationwide coverage and strong performance across urban and rural areas
  • KDDI (au) – Reliable network with excellent balance of speed and stability
  • SoftBank – Fast speeds in major cities and tourist zones

While NTT Docomo is often considered the largest network in Japan, access to its network is limited for short-term travel eSIM products. For international travelers, eSIM services typically operate on partner networks — and in many cases, KDDI offers the most consistent and reliable experience for short-term visitors. Network performance can also vary depending on location, congestion, and time of day. That’s why choosing the right eSIM provider matters. We continuously analyze real-world network performance across Japan through our independent testing program. Explore real-world performance insights in our Connectivity Lab below.

02

Real-World Performance

Connectivity Lab is our in-house research initiative where we test real mobile network performance across Japan. Instead of relying on theoretical coverage, we measure actual speeds, latency, and stability in real travel scenarios — including city centers, transit systems, and high-density tourist areas.

Our latest reports include:

Tokyo Network Performance Test

Real-world speed and latency results across major districts.

Japan Sakura Season Connectivity Report (2026)

Network performance under peak tourist congestion.

Narita/Haneda Airport Field Test

Performance insights from one of Japan’s busiest travel destinations.

These insights help travelers choose the most reliable eSIM for their trip — based on real data, not assumptions.

First time using eSIM for your trip to Japan?

Count on us for your stress-free eSIM experience.

01

What is eSIM?

An eSIM is a digital SIM built into your phone.
Instead of inserting a physical card, you install a mobile plan by scanning a QR code.

In practice, it means:

  • No waiting at the airport
  • No swapping SIM cards
  • No risk of losing your original SIM

You land, turn it on, and you’re connected.

02

Is my device compatible?

Most modern smartphones support eSIM — but not all.

  • iPhone: XR and newer models usually work
  • Android: Recent Samsung Galaxy and Google Pixel devices are typically supported

However, some devices (especially those from China or Hong Kong) may not support eSIM.

The easiest way to be sure:
Check our supported device list or your phone settings before purchase.

Frequently asked questions about eSIM Japan

Can I get eSIM in Japan?

Absolutely, you can get an eSIM anytime, anywhere, provided you have a compatible and unlocked device.
For the complete list of supported device models, please visit our guide page.
To determine whether your device is locked or unlocked, please refer to the brand-specific instructions for your phone:

For Apple Devices:

01. Access [Settings] – [General] – [About] and scroll down
02. If you see “Network Provider Lock – No SIM restrictions” and “Digital SIM – IMEI (number will appear),” your phone supports eSIM.
03. If you encounter “SIM restrictions,” your phone does not have eSIM support.

For Samsung & Google Devices:

01. Access [Settings] – [Connections] – [Mobile networks].
02. Choose [Networks operators]
03. If you see multiple available networks, your phone is likely unlocked and eSIM-compatible.
04. If only one result is visible, or the option to search for networks is unavailable, your phone may be carrier-locked. In such a scenario, you’ll need to contact your domestic carrier to unlock your phone before using an eSIM.

Which eSIM is best for Japan?

The best eSIM for Japan depends on network quality and reliability, not just price.
That’s why high-quality plans that use top-tier Japanese networks tend to perform best — especially in busy cities, stations, and transit.
Our plans are designed for travelers who want a fast, stable connection across Japan.
– Data-only eSIM (no local number)
– Works with WhatsApp, FaceTime, Skype, and more

How do I set up eSIM in Japan?

Setting up your eSIM is quick and simple.
After purchase, you’ll receive a QR code by email.
Just follow these steps:

1. Connect to Wi-Fi
Make sure you have a stable internet connection.

2. Add your eSIM

If scanning doesn’t work
You can also install it manually by entering the activation details provided in your email.

Which is the ideal eSIM package for Japan?

For most travelers, unlimited data plans are the best choice.
They give you the freedom to use maps, streaming, and hotspot without worrying about running out of data — especially during long travel days.

Unlimited plans
Best for heavy and flexible usage.
After high-speed data is used, speeds may be reduced, but you stay connected throughout your trip.

Fixed data plans (3GB–30GB)
A lighter option if you use less data and want to control your usage.

Asia plans
Ideal if you’re traveling across multiple countries.

Our recommendation:
If you want a stress-free experience, go with an unlimited plan.

Does the eSIM plan support voice calls and SMS?

Our eSIM plans are data-only, so they don’t include a local phone number.
However, you can still make calls and send messages using apps like:

– WhatsApp
– FaceTime
– Skype
– Telegram

As long as you have data, you can stay fully connected.

How long does it take to receive the QR code?

You’ll receive your eSIM QR code by email within minutes — usually under 15 minutes after payment.

Didn’t receive it?
– Check your spam or promotions folder
– Make sure your email address was entered correctly
– Check the email linked to your payment

If you still can’t find it, contact us and we’ll resend it quickly.

How do I get assistance?

You can reach our support team anytime.

Email: [email protected]
Chat: WhatsApp (Available 24/7)

We’re here to help with setup, plans, or any issues — whenever you need.

How can I confirm my eSIM is activated?

You can quickly check if your eSIM is active:

– You see signal bars or a network name on your phone
– Mobile data works (e.g., you can browse or use apps)

If both are working, your eSIM is ready to use.

Still not sure?

Check your device settings to confirm the eSIM profile is turned on.

Do I need to turn off my original SIM?

We recommend turning off your original SIM to avoid unexpected roaming charges.
This ensures your phone uses only the eSIM for data while you travel.

Want to keep your number active?

You can keep your original SIM on to receive calls and SMS.
Just make sure your mobile data is set to the eSIM to prevent extra charges.

Do I need to enable data roaming?

Yes — make sure data roaming is turned on for your eSIM.
This allows your eSIM to connect to local networks in Japan.

Important
To avoid unexpected charges, keep your mobile data set to the eSIM, not your original SIM.

How can I check my data balance?

You can check your data usage directly in your phone’s settings.

On iPhone: Settings > Cellular (Mobile Data)
On Android: Settings > Network & Internet > Data usage

Quick tip

Your device shows estimated usage, not exact remaining data.

For detailed usage information, feel free to contact us.

What happens if I run out of data or my plan expires?

Your data will stop working once your plan runs out or expires.

Need more data?

You can easily top up in seconds using the link in your QR code email.
No reinstall needed — just add more data and stay connected.

How can I remove the eSIM after my trip?

You can remove your eSIM anytime from your phone’s settings.
Go to Settings > Cellular (or Mobile Data), select your eSIM, and remove it.

Good to know
Removing the eSIM won’t affect your original SIM or phone number.
