How It Works
Purchase & receive QR code
Complete checkout in under 2 minutes. Your eSIM QR code arrives by email instantly — no waiting.
Install on your device
Open Settings on your phone and scan the QR code. Takes under 2 minutes on any compatible device.
Arrive & connect
Switch to your Japan eSIM on arrival. Instant data — no shops, no queues, no roaming shock.
Important Information
When validity starts
Your 15 Days validity begins when you first activate and use the eSIM in Japan — not at the time of purchase.
Data type
Data only plan. Use WhatsApp, iMessage, FaceTime, email and all data-based apps. Your UK number stays active for calls and texts.
Hotspot / Tethering
Hotspot availability depends on your device and network. Check Settings on arrival.
Fixed Data
Fixed data plan. Once the data allowance or validity period expires, a new plan may require reinstallation.
Fair usage
Full-speed data up to your included allowance. After the allowance is used, data may slow or stop. No unexpected charges — when it is used, it is used.
Device compatibility
Works on all eSIM-compatible unlocked devices: iPhone XS or later, Samsung Galaxy S20 or later, Google Pixel 3 or later, and most modern flagships.
