To make the most of your trip to Osaka in 2026, staying connected is essential. Many travelers choose Pocket WiFi to avoid the hassle of hunting for free Wi-Fi spots and to eliminate security concerns. While eSIMs have become a popular and convenient option—and we do offer them ourselves—as of March 2026, Pocket WiFi remains the preferred choice for many of our customers.
Stable internet is indispensable for a stress-free experience in Osaka. Pocket WiFi offers travelers benefits that go far beyond simple connectivity.
In 2026, the number of people using eSIMs has increased significantly because they don't require a physical card. In terms of pure convenience—being able to buy and set them up anywhere—eSIMs have many advantages. However, the reality is that Pocket WiFi offers greater benefits depending on your specific needs, which is why it remains a popular choice for many travelers.
1. Unbeatable Cost Performance
eSIMs are designed for use on a single smartphone, meaning everyone in your group needs to buy their own. For a group of three, renting one Pocket WiFi and sharing it is far more affordable than buying three separate eSIMs.
2. Support for Multiple Devices
If you need to connect an iPad or laptop, tethering via an eSIM will drain your smartphone's battery rapidly. Additionally, many eSIM plans have restrictions on tethering. A dedicated Pocket WiFi allows you to connect multiple devices to high-speed internet simultaneously without worrying about your phone's battery.
3. Guaranteed Device Compatibility
eSIMs are limited to specific compatible devices and often require complex conditions like SIM-locking to be removed. Pocket WiFi works with any device that has Wi-Fi capability, ensuring a 100% success rate.
4. High-Speed, Large-Capacity Data
Pocket WiFi utilizes major carrier networks, providing a stable connection with high data limits. Compared to many eSIM plans, you generally get access to significantly more data.
| Comparison Item | eSIM | Pocket WiFi |
|---|---|---|
| Setup Difficulty | Moderate (QR scanning, etc.) | Easy (Password entry only) |
| Cost (Group of 3) | High (3 separate plans) | Very Low (Share 1 device) |
| Multi-Device Support | Not recommended | Optimized (PC/Tablets OK) |
| Phone Battery Life | Drains quickly | Saves battery |
| Network Stability | Depends on phone specs | Stable (Dedicated device) |
Solo travelers who are comfortable with technical settings and want to minimize their luggage as much as possible.
Families, groups, or business travelers using laptops and tablets. Ideal for those who want to skip setup hassles and keep costs low.
If you are traveling alone and want to pack light, an eSIM is a great, convenient choice with no need for returns.
