Before using eSIM Japan

eSIM technology offers several advantages to business travelers:

1. Convenience: The use of eSIM eliminates the need for physically swapping SIM cards when traveling internationally or changing carriers. Users can remotely activate a data plan on their eSIM, saving valuable time and effort.

2. Cost-Effectiveness: Travelers who frequently travel abroad can benefit from eSIM’s cost savings. Rather than purchasing a new SIM card in each country, which can be expensive, eSIMs enable users to activate data with local carriers, taking advantage of favorable local rates.

3. Flexibility: eSIMs allow for quick and effortless switching between carriers and plans without the requirement of physically changing SIM cards. This flexibility is particularly valuable for business travelers who need to adjust their plans based on their travel schedules and locations.

4. Security: eSIMs offer enhanced security compared to physical SIM cards because they are tamper-proof and cannot be removed from the device. This feature is crucial for business travelers who may carry sensitive data on their devices. Moreover, utilizing data through eSIM connections offers enhanced security compared to connecting through public Wi-Fi networks.

5. Reliability: eSIMs provide a more dependable connection as they are not susceptible to physical wear and tear like traditional SIM cards. This reliability is especially important for business travelers who rely on a stable connection for work-related tasks such as video conferencing and sending critical emails.

6. Environmental Benefits: eSIMs are considered more environmentally friendly than traditional physical SIM cards. They reduce waste and pollution associated with the production and disposal of physical plastic cards.

Traditional physical SIM cards are typically composed of non-biodegradable materials, including plastic and metal, which decompose slowly and contribute to environmental pollution. Additionally, the production of physical SIM cards consumes energy, water, electricity, and raw materials.

In contrast, eSIMs are integrated into the device’s hardware, eliminating the need for physical cards. Consequently, eSIMs are more eco-friendly, reduce waste and pollution, and lower the carbon footprint of the mobile industry by reducing energy and resource consumption during SIM card production, shipping, and disposal.

In summary, eSIMs offer a sustainable and environmentally friendly solution for mobile connectivity compared to traditional physical SIM cards. Their ability to reduce waste and pollution contributes to a more environmentally conscious future.

When an eSIM-supported phone has a physical SIM card, adding an eSIM data plan from a different operator typically won’t interfere with the existing SIM card. However, it’s possible that some adjustments may be necessary in the phone’s network settings to ensure the smooth operation of both the physical SIM and eSIM.

Most smartphones support dual-SIM functionality, allowing users to have two active SIM cards simultaneously. With dual-SIM support, one SIM card can be designated for voice and SMS services, while the other handles data services.

Please be aware that configuring dual-SIM settings may vary depending on your specific device and mobile network provider. We recommend you consult the instructions provided by your device provider.

You’re able to cancel the order before the activation of an eSIM.

After this 180-day period has passed, the eSIM plan will expire.
