Stay connected in Japan without roaming fees.
Saily offers affordable data plans that you can access via an eSIM. Unlike traditional travel SIM cards, Saily plans provide instant activation & allows you to keep your existing phone number.
eSIM (embedded SIM) technology offers travellers a convenient alternative to traditional roaming charges and physical SIM cards when visiting Japan. These digital SIM cards can be activated instantly without requiring a physical swap, allowing users to maintain their primary phone number while accessing local data networks.
Key Benefits of eSIM for Japan Travel:
Cost-effective: Significantly cheaper than international roaming fees
Instant activation: No need to visit stores or wait for physical delivery
Dual number capability: Keep your home number active while using local data
Flexible top-ups: Add more data as needed through mobile apps
Wide coverage: Access to Japan's extensive mobile network infrastructure
How an eSIM Works: eSIM plans are purchased digitally and activated by scanning a QR code or entering activation details. Once activated, your device connects to local Japanese networks, providing the same data speeds and coverage as domestic users enjoy.
