Ways to Be Connected Abroad in Tokyo

To ensure you have internet access when traveling abroad, there are main ways to connect to the network:

• International Roaming(IR)

Before traveling to Tokyo, you can contact your mobile carrier to see if they offer affordable data roaming plans for international travel. By activating international roaming, you can use your mobile data to access the internet while abroad. However, the IR usually charges a much higher rate than the local mobile data and ensures you have the right plan in place before traveling.

• Pocket Wi-Fi

Consider renting a pocket Wi-Fi device, also known as a portable hotspot. This small device allows you to create a Wi-Fi network that you can connect multiple devices to. Many rental companies offer convenient pickup and drop-off locations at airports or hotels.

• Public Wi-Fi

Use the public Wi-Fi networks available in Tokyo. Look for the " Metro_Free_Wi-Fi" network at subway stations or the " Japan Connected-free Wi-Fi" network in various locations across the city. These networks require initial registration but provide free internet access once connected. But it cannot be the long-term option for you, cuz for public Wi-Fi is not always available anywhere you go.

*** Remember to always prioritize the security of your personal information and devices when using public Wi-Fi networks. Consider using a virtual private network (VPN) for added protection.

• Local SIM Card

Purchase a local SIM card upon arrival in Tokyo. This will allow you to have a local phone number and access to a mobile data plan for internet connectivity. You can find SIM cards at airports, electronics stores, and convenience stores throughout the city. By using a local SIM card, you can access the local mobile network, make calls, and utilize data at local rates. Before purchasing and inserting a new SIM card, make sure that your phone is unlocked.

• eSIM

If your device supports eSIM technology, you have the ability to connect to the network abroad using an eSIM. This process includes digitally activating an eSIM plan without needing to switch SIM cards on your phone manually and hopping in the line for a SIM on the premises. Make sure to check with your current carrier or local carriers at your destination to see if they offer eSIM plans.

Among the many available options, what is the most convenient and cost-effective way for common travelers to access networks in a foreign country?

ESIM?

eSIM technology has revolutionized the way we connect and communicate in a rapidly evolving digital landscape, and its popularity is growing worldwide. eSIM, a new concept that has emerged in recent years, may not be something you are familiar with. So, let's dive into and grasp the concept of what on earth eSIM is.

An eSIM, or embedded SIM, is a type of SIM card that is permanently integrated into a device rather than being a removable physical card. Instead of having a physical chip, an eSIM consists of software installed onto an eUICC (Embedded Universal Integrated Circuit Card) chip that is permanently attached to the device. Traditional SIM cards, in contrast to eSIMs, need to be physically inserted and removed since they are not integrated into the device's hardware. By wirelessly programming this small chip, users can switch between carriers and activate mobile plans without a physical SIM card.

Edges of Tokyo ESIM Compared to the Other Ways

Convenience, flexibility, improved security, remote management, cost...as a matter of fact, there are multiple reasons to recommend an eSIM over other alternatives:

Smaller Form Factor

eSIMs are available in much smaller sizes compared to traditional SIM cards, allowing for more flexibility in device design and enabling their use in smaller devices.

Improved Security

eSIMs provide enhanced security features, such as remote provisioning and authentication mechanisms, making them less susceptible to physical tampering or unauthorized access.

Flexibility and Convenience

With an eSIM, you can easily switch between different network providers without the need to physically change SIM cards. This flexibility is especially useful for frequent travelers or people who want to switch between work and personal numbers on a single device.

Space-Saving Design

The absence of a physical SIM card slot in eSIM-enabled devices allows for more efficient use of internal space, enabling manufacturers to incorporate additional features or optimize the design for waterproofing and durability.

Simplified Setup Process

Activating an eSIM is typically a straightforward process that can be done remotely, eliminating the need for physical SIM card handling and simplifying the initial device setup or switching between carriers.

Remote Management

eSIMs enable over-the-air (OTA) management, which means that network operators or service providers can remotely update or modify subscription plans, ensuring a seamless user experience and reducing the need for physical SIM card replacements.

Dual SIM Capability

eSIMs allow users to have dual SIM functionality on their devices, enabling them to use two different phone numbers simultaneously, whether it's for personal and work purposes or for accessing different networks while traveling.

Future-Proof Technology

As eSIM adoption continues to grow, more carriers and service providers are offering support for eSIM. This makes eSIM a future-proof technology that provides compatibility with evolving network technologies and global connectivity options.

Environmental-Friendly Way

With eSIM technology, mobile connectivity can be achieved more sustainably. There is often substantial waste generated with traditional SIM cards as they are frequently replaced and discarded. By using eSIM, the need for physical cards is eliminated, resulting in a reduction of plastic waste and shipping materials. eSIM's eco-friendly aspect makes it a more sustainable choice for the future.

Depending on your specific device model and network provider's offerings, please note that the availability of certain features, such as dual SIM capability or carrier support, may vary.
