Battery Life and Portability

Mobile Wi-Fi devices are compact and lightweight, making them easy to carry in a pocket or bag. Battery life varies by model but generally lasts between 8 to 12 hours on a full charge. For extended outings, carrying a power bank can ensure uninterrupted connectivity.

Comparing Mobile Wi-Fi to SIM Cards

For foreigners deciding between “SIM Cards in Japan” and mobile Wi-Fi, the choice often depends on individual needs:

• Solo Travelers: SIM cards may be more cost-effective for individuals who only need connectivity for a single device.
