Wi-Fi or SIM Card?
Planning a trip to Japan and wondering how to stay connected? You’re not alone. One of the most common questions travelers ask is:
“Should I get a SIM card or rent a Wi-Fi device?” While both options work, portable Wi-Fi—especially Car Wi-Fi—offers flexibility, convenience, and unmatched coverage that SIM cards often can’t keep up with.
Let’s dive into why Wi-Fi is your best travel companion in Japan, and introduce an exciting new option for road trippers: Car Wi-Fi devices!
🚀 Why Wi-Fi Beats SIM Cards in Japan
Imagine having your own high-speed mobile internet hub wherever you drive. A Car Wi-Fi device is a compact portable router that plugs into your rental car, instantly turning it into a moving hotspot. Whether you’re navigating Tokyo’s city streets or exploring Hokkaido’s mountains, you and your passengers stay connected effortlessly.
Wider Coverage
High-quality portable Wi-Fi routers (like Car Wi-Fi) automatically switch between major mobile carriers for the best signal — even in remote areas where SIM cards may struggle.
Connect Multiple Devices
Need internet for your phone, tablet, and laptop? A Wi-Fi device handles them all — unlike a SIM card, which is tied to one device.
Shared Connection
Traveling with family or friends? Share one Wi-Fi device — no need to buy multiple SIM cards.
