1. What's the difference between pocket WiFi and an eSIM?
Pocket WiFi is a physical device that creates a personal hotspot — ideal for groups sharing one connection. An eSIM is a digital SIM built into your phone — cheaper for solo travellers with no device to carry. If you're travelling alone and your phone supports eSIM, an eSIM is almost always better value. For groups of 3+, pocket WiFi often works out cheaper per person.
2. How many devices can connect to pocket WiFi?
Most rental pocket WiFi devices support up to 10 simultaneous connections, making them ideal for families or small groups where everyone wants their own phone or tablet connected. Connection speed may slow slightly with multiple devices active at once, but in practice it's rarely noticeable for typical tourist use — maps, messaging, and light browsing.
3. How long does a pocket WiFi battery last in Japan?
Most rental pocket WiFi batteries last 6–10 hours of continuous use. Ninja WiFi devices typically last around 8 hours. For a full day of sightseeing, you may need to recharge during the day — Global WiFi includes a free powerbank, which solves this problem. Carrying a charging cable is always recommended.
4. Where do I pick up and return pocket WiFi in Japan?
Most providers offer airport pickup at Narita, Haneda, Kansai, and Fukuoka airports. Return is usually at the airport on departure — drop it in the dedicated return box before boarding. Some providers also offer hotel delivery. Book in advance to guarantee availability, especially during busy travel seasons like spring (cherry blossom) and autumn.
5. Should I get pocket WiFi or an eSIM for my Japan trip?
For solo travellers: an eSIM is cheaper, simpler, and means one less device to carry. For couples or groups: pocket WiFi often costs less per person, especially for 3+ people sharing one device. If you need to share connectivity across a group and everyone's using their own phone, pocket WiFi is the better choice. If you travel alone and have a compatible phone, get an eSIM.
