1. What is eSIM?

eSIM stands for "embedded SIM," which is an electronic SIM card built into the device, rather than a physical SIM card. Currently, eSIM and traditional SIM cards are the two most commonly used types. Compared to physical SIM cards, eSIM helps keep mobile devices compact and simplifies switching between carriers, which is especially convenient when traveling or going on business trips.

In over 55 countries, especially in Europe and North America, it’s already commonly used. By 2025, it’s expected that nearly half of all smartphones shipped will support eSIM.

As more people consider either switching to an eSIM provider or purchasing an unlocked phone to use eSIM, we’ll now introduce the benefits and drawbacks of eSIM.

First, let's outline the common advantages of all eSIMs:

No Need to Replace Physical SIM Cards: 

eSIM is embedded digitally, meaning there's no need to physically swap SIM cards. By scanning the eSIM QR code received via email, you can easily install it on your phone and start using it immediately.

Easy Setup Online: 

The eSIM process can be completed entirely online. For example, when switching phones or carriers using a traditional SIM card, you often have to wait for the new SIM card to be issued and shipped. With eSIM, you can input the necessary information online and begin using it within the same day.

Use Multiple Lines: 

On devices that support both eSIM and traditional SIM cards (Dual SIM), you can use multiple lines on one phone. For example, if you usually use a physical SIM card, you can use an eSIM when traveling abroad, saving you from purchasing a new phone.

This is especially useful when traveling, as eSIM is more user-friendly compared to traditional SIM cards or international data roaming, which is why it has gained popularity in recent years.

For travelers, eSIM is the perfect solution to reduce cumbersome procedures and set up efficient communication. It is particularly effective in situations like:

2.1.1 When you need internet access abroad:

You don’t need to purchase a traditional SIM card; you can buy and install an eSIM plan online and be connected immediately.

2.1.2 Short-term stays or frequent travel: 

When traveling between multiple countries, you don’t have to buy new SIM cards at each destination, saving a lot of time and effort.

2.1.3 To save on communication costs: 

Compared to international roaming, eSIM plans are often more affordable, leading to significant cost savings.

Despite the many benefits, there are still some drawbacks to eSIM, especially when considering its use abroad. Below are the key disadvantages of eSIM:

1. Difficulties with Device Switching:

Switching devices with eSIM is more complicated than using traditional SIM cards. With a physical SIM, you can simply swap cards, but with eSIM, the process requires online procedures, which may be challenging for users unfamiliar with it.

2. Limited Carrier Support: 

Not all carriers support eSIM. In Japan, carriers like au and some MVNOs offer eSIM, but many others don’t. Before considering eSIM, make sure the carrier you plan to use supports it.

3. Limited Device Compatibility: 

The number of eSIM-compatible devices is still limited compared to traditional SIM cards. In Japan, there is a smaller selection of eSIM-supported devices. However, with increased eSIM support from carriers, this selection is expected to grow.

4. Activation Lock Requires Additional Device: 

Sometimes, an additional device is needed to disable the activation lock when setting up eSIM, adding to the complexity of the process.

5. Internet Connection Required: 

eSIM setup requires an internet connection. For example, when scanning the QR code to install the eSIM, you need to be connected to Wi-Fi, which may be challenging in some areas with unstable internet.

6. Limitations for Overseas Use: 

There may be restrictions when using eSIM abroad, particularly depending on the regulations of the local carriers. Some countries may not support eSIM, or only specific eSIM providers may be available.

To use eSIM abroad, first purchase an eSIM plan from a brand's official website or Amazon. After purchasing, you will receive a QR code, which you can scan to install eSIM on your smartphone.

With this, you can start using the internet smoothly without needing to buy a SIM card or visit a store upon arrival.
