eSIM Basics | How It Differs from SIM  and Pocket WiFi

When traveling abroad, choosing between eSIMs, mobile carrier roaming, or renting a Pocket WiFi can be confusing. Each option has its own pros and cons, but eSIMs stand out for their speed and simplicity when it comes to getting connected. In this section, we’ll explain how eSIMs differ from traditional SIM cards and cover the key advantages and disadvantages of using an eSIM.

From Purchase to Activation | eSIMs Are Ready to Use in Minutes

With an eSIM, you can purchase online and activate it in just 5–10 minutes by scanning a QR code on your smartphone.

If you set it up before your trip, you’ll be able to start using mobile data as soon as you arrive in Japan. Simply enable the eSIM in your phone’s settings and turn on data roaming if needed.

On the other hand, physical SIM cards require shipping time when ordered online—usually at least one day. While buying one at an airport or local shop allows same-day use, you’ll still need to swap the SIM and manually configure settings like the APN.

If speed and convenience matter, eSIMs are clearly the better choice. They’re especially ideal for short-term travel or business trips where quick setup and immediate connectivity are essential.

3 Benefits of Using an eSIM

eSIMs offer several advantages over traditional physical SIM cards.

First, there's no need to swap out SIM cards—everything is handled digitally, so you won’t risk losing a tiny SIM while traveling. Since the entire process from purchase to setup can be completed online, it saves both time and hassle.

Another key benefit is that you can set up your eSIM in advance before leaving for Japan. This allows you to take your time choosing the right plan that fits your trip length and data needs.

Once you arrive, your eSIM is ready to go—just activate it in your phone’s settings.
One of the biggest perks is being able to connect to the internet the moment you land at the airport.

🔍

①Online Purchase (Choose data capacity and duration on our official site to purchase a plan.)

🔍

②QR Code Scanning (After payment completion, a QR code will be sent to your email immediately. Scan the QR code from your phone settings to install the eSIM. Complete setup while in your home country!)

🔍

③Start Using in Japan (After arriving in Japan, simply turn on the eSIM connection! You'll be able to use the internet immediately for your Japan trip.)

Drawbacks and Limitations of eSIMs

While eSIMs are highly convenient, there are a few important points to keep in mind.

cannot be used on incompatible phones

First, eSIMs cannot be used on smartphones that don’t support eSIM technology. Some older models or budget devices may not be compatible, so it’s essential to check whether your phone supports eSIM before purchasing.

Setup may be tricky

If it’s your first time using an eSIM, the setup process—such as scanning a QR code or enabling mobile data—might feel a bit tricky. In that case, we recommend choosing a provider that offers clear instructions and reliable customer support.

Use QR code on the correct device

Also, an eSIM can only be installed and used on the device it was first activated on. Since QR codes are usually issued once and cannot be reissued, make sure to scan it on the correct phone.

How to Check EID on iPhone and Android

The easiest way to check your EID is to dial "*#06#" using the default phone app on iPhone or Android.

If your smartphone supports eSIM, making this call will display "EID (32-digit eSIM identification number)". If you can confirm the EID, you can use eSIM both domestically and internationally.

Survey of Japan's Internet Penetration Rate | Introduction to Major Telecommunications Carriers!

We have surveyed Japan's internet situation, including free Wi-Fi availability!

Japan's Free Wi-Fi Penetration Rate

All major airports in Japan with direct international flights are equipped with free Wi-Fi.

However, outside of tourist destinations like Tokyo, Osaka, and Kyoto, free Wi-Fi is not necessarily widely available throughout Japan.

Most free Wi-Fi services provided in Japan require procedures such as "email registration," "agreement to terms of use," and "SNS authentication," which many overseas visitors find cumbersome to use.

Additionally, compared to Western countries, Japanese companies do not strongly embrace the concept of using free Wi-Fi to extend customer stay time, and many restaurants and cafes do not offer free WiFi.

In Japan, for communication during overseas travel, rather than relying on free Wi-Fi, it is safer to use encrypted internet connections such as eSIM or rented pocket Wi-Fi.

How Are Japan's Internet Connection Speeds?

(Source: SPEEDTEST Official)

Japan's mobile network speeds, as an island nation, are slower than the global average. Please refer to the following table for detailed data on Japan's internet communication speeds.

The above are reference values using "SPEEDTEST," a famous speed testing site. (As of May 2025)

While mobile networks may be inferior, Japan's fixed broadband (Wi-Fi) has actual measured speeds more than twice the global average, making it extremely fast.

In Japan, Wi-Fi environment construction using fiber optic lines has been promoted centered around NTT, so there is a high possibility of using comfortable networks in hotels and ryokans.

Japan's Three Major Telecommunications Carriers

While Japan has many companies providing mobile networks, most of them use the networks of the three major companies: "NTT Docomo," "KDDI," and "Softbank."

Let's look at the average execution speeds and coverage areas of Japan's three famous telecommunications carriers.

Network Carrier	Coverage Area※1	eSIM Providers Using This Network	Communication Speed※2	Provider
NTT docomo (Coverage Details)		JapanConnect eSIM, Ubigi	47.09Mbps	NTT
KDDI (au) (Coverage Details)		JapanConnect eSIM, Holafly, Ubigi, airalo, Saily, Nomad	46.23Mbps	KDDI
Softbank (Coverage Details)		JapanConnect eSIM, airalo, Nomad, World eSIM	46.90Mbps	Softbank

※1 Coverage areas reference nperf.com coverage maps (tap to open)
※2 Communication speeds reference SPEEDTEST.com

Japan's largest telecommunications carrier is NTT, and its subsidiary NTT Docomo covers a very wide area throughout Japan, including urban areas, tourist destinations, mountainous regions, and coastal areas.

However, NTT Docomo is prone to radio interference in crowded environments such as buses and trains, which can cause communication instability.

On the other hand, KDDI (au) and SoftBank may be somewhat inferior to Docomo in coverage areas of mountainous and coastal regions, but they are evaluated as having excellent communication speed and stability in major urban areas and tourist destinations.

When comparing eSIM options by telecommunications carrier, it is advisable to choose eSIM services that partner with each eSIM provider based on the areas you plan to visit.

Prepaid SIMs Sold at Japanese Airports Are Expensive

Many prepaid SIMs are sold at Japanese airports, and recently they can even be purchased from vending machines. While convenient as they can be used immediately upon arrival in Japan, the prices are quite high due to the demand.

Let's take a look at the prepaid SIM prices sold at Narita Airport for reference.

As shown above, SIM card sales counters at airports have aggressive pricing strategies.

FAQs

Which eSIM is recommended for Japan?

Top recommended eSIMs for Japan travel include JapanConnect eSIM, Airalo, and Holafly. JapanConnect eSIM offers multi-network access with Japan’s major carriers such as au (KDDI), SoftBank, and NTT Docomo, making it highly reliable in terms of speed and connection stability. If you prefer unlimited data, Holafly is a solid choice. For travelers who want affordable pricing with small data volumes and flexible plans, Airalo is a popular option.

Can I purchase a Japanese eSIM?

Yes, Japanese eSIMs can be easily purchased online. Services like JapanConnect eSIM, Nomad, and Airalo offer eSIM plans that can be activated either before your trip or immediately upon arrival. You don’t need a physical SIM card, and most eSIM-compatible unlocked smartphones are supported.

Are there eSIMs for tourists in Japan?

Yes, many eSIM plans are specifically designed for inbound tourists visiting Japan. Providers such as JapanConnect eSIM, Holafly, and Airalo offer plans ranging from 3 to 30 days, using major Japanese carrier networks like NTT Docomo, au, and SoftBank.

Which is better for Japan: Airalo or Ubigi?

Generally, Airalo is more popular in Japan due to its affordable pricing and flexible options for data and duration. Ubigi may offer faster speeds in specific areas where NTT Docomo’s 5G is available, providing wide and stable coverage. However, for cost-effectiveness and ease of use, many travelers prefer Airalo.

Can I buy an eSIM at a Japanese airport?

In many cases, eSIMs can be purchased from vending machines at Japanese airports. However, due to the high installation and maintenance costs, airport eSIMs tend to be more expensive. It is recommended to purchase an eSIM online before arrival and activate it using airport Wi-Fi. Services like JapanConnect eSIM and Airalo support instant issuance, so there is no need to look for a SIM vendor upon arrival.

Which is better for Japan travel: eSIM or pocket WiFi?

For solo travelers, an eSIM is generally more convenient. It eliminates the need to rent or return a separate device, allowing you to connect directly with your smartphone. On the other hand, if you’re traveling in a group or require unlimited data, pocket WiFi may be worth considering. For short trips or individual use, eSIMs are often superior in both cost and convenience.
