Staying connected in Japan is important for travellers, especially for non-Japanese speaking travellers. With options like pocket Wi-Fi and eSIM cards, it can be difficult to decide which is best for your needs. In this guide, we’ll compare these two solutions to help you make an informed choice for your trip.
What’s the Difference Between Pocket Wi-Fi and eSIM Cards?
Before diving into specifics, let’s understand the basics of pocket Wi-Fi and eSIM cards:
Feature | Pocket Wi-Fi | eSIM Card |
Device Requirement | Portable router | Compatible smartphone |
Connectivity | Creates a Wi-Fi hotspot for devices | Connects directly to your phone |
Setup | Pick up or arrange delivery | Activate online via QR code or app |
Cost | Daily rental fee | Pay-as-you-go or subscription |
Portability | Requires carrying and charging | Integrated into the phone |
Pocket Wi-Fi is essentially a portable router that creates a mobile hotspot, allowing multiple devices to connect. On the other hand, an eSIM is a digital SIM embedded in your smartphone, eliminating the need for physical hardware. Both have their pros and cons, as we’ll explore in detail.
Understanding Internet Needs for Japan Travel
Japan’s seamless infrastructure makes it a traveler’s dream, but reliable internet is crucial. Here are some typical use cases to consider:
- Navigation: Access maps to explore cities, find landmarks, and ensure you never get lost.
- Translation Apps: Essential for communication, reading menus, and understanding signage.
- Social Media: Stay connected with friends and family by sharing your experiences in real-time.
- Streaming and Entertainment: Whether it’s streaming a movie on a train or uploading a video, stable internet is key.
- Work Needs: For business travelers, having a stable connection ensures you’re prepared for meetings and emails.
Connectivity Challenges in Japan
While Japan’s urban areas boast excellent network coverage, some rural or mountainous regions can pose connectivity challenges. Both pocket Wi-Fi and eSIM cards provide robust solutions, but an eSIM’s ability to switch between networks often ensures more consistent coverage in these areas.
When to Choose eSIM Over Pocket Wi-Fi in Japan
Solo or small group travel benefits
For individual or small group travelers, eSIM cards are an excellent choice. They eliminate the need to carry extra devices and chargers, offering a hassle-free experience. Activating an eSIM is quick and easy, making it ideal for tech-savvy solo adventurers.
Business Trip Advantages
Business travelers often need reliable internet for video calls, emails, and file sharing. An eSIM for business ensures consistent, high-speed connectivity without juggling extra devices. Plus, eSIMs allow easy top-ups, so you’re never left without data during important tasks. Learn more about the benefits eSIM for business here.
Long-Term Stay Considerations
For extended stays, eSIMs are cost-effective and convenient. Many providers, like Orange Travel eSIM Japan offer affordable plans in Japan, tailored to long-term travelers. Without the hassle of picking up or returning devices, eSIMs are a practical choice for students or professionals staying for weeks or months.
Urban vs. Rural Coverage
Pocket Wi-Fi provides strong signals in cities and is great for areas with steady infrastructure. However, eSIMs often shine in rural areas, as they can switch between multiple networks for the best signal. If you plan to explore off-the-beaten-path destinations, an eSIM ensures you’ll stay connected.

Costs Associated with Pocket Wi-Fi vs eSIM in Japan
One of the deciding factors for many travelers is cost. Let’s break it down:
Pocket Wi-Fi Costs
- Daily Rental: Prices typically range from $5 to $10 per day, depending on the provider and data allowance.
- Deposit: Some providers require a refundable deposit for the device.
- Data Limits: While many plans offer “unlimited data,” some may throttle speeds after reaching a fair usage limit.
- Additional Costs: Be prepared for potential late return fees if you forget to return the device.
eSIM Costs
- Plan Options: Prices start at $25 for a 14-day plan, with various options based on data needs.
- Data Flexibility: Many eSIMs allow top-ups, so you only pay for what you use.
- No Extra Hardware: eSIMs eliminate the need for deposits or physical devices, reducing upfront costs.

Hidden Costs to Watch Out For
Be cautious of “unlimited data” claims. While pocket Wi-Fi and eSIMs may advertise unlimited data, some providers throttle speeds after reaching a usage cap. Always read the fine print to ensure your chosen plan meets your needs. Otherwise, you can choose Orange Travel plans for high speed data for all plans.
Making the Right Choice Between Pocket Wi-Fi and eSIM Card for Your Japan Trip
Here’s a quick guide to help you decide:
Choose Pocket Wi-Fi if:

- Locked Phones: If your phone is locked, pocket Wi-Fi is your only option.
- Unlimited Data Needs: Be mindful of potential throttling but enjoy higher initial data allowances.
- Device Compatibility: Older phones not compatible with eSIMs can still use pocket Wi-Fi.
Choose eSIM if:
