An eSIM is a digital SIM built into your phone. With a SimYak Japan eSIM you get mobile data the moment you arrive — no physical SIM, no shop visits. Just scan a QR code and connect.
After purchase you'll receive a QR code by email. Go to Settings → Cellular / Mobile Data → Add eSIM, scan the code and turn it on. It takes under a minute (you'll need Wi-Fi or data to install).
Most phones released from 2018 onwards support eSIM — iPhone XS+, Google Pixel 3+, Samsung Galaxy S20+. Check yours with our Check device compatibility tool before you buy.
Yes. Your SimYak Japan eSIM works alongside your regular SIM, so you keep your home number for calls and texts while using Japan data.
Top-ups aren't available — just buy another Japan plan anytime and it activates instantly, so you're back online within seconds.
Yes. You can share your Japan data via personal hotspot or tethering with a laptop, tablet or other devices.
No. SimYak eSIMs are data-only, so they don't come with a local number. Keep your home SIM active for calls and texts, or use apps like WhatsApp and FaceTime over data.
For light use (maps, chat, email) 1–3GB is usually enough for a short trip. For social media, streaming and daily use choose 5–20GB — or pick an Unlimited plan for worry-free travel in Japan.
An eSIM is lighter, cheaper and instant: there's no extra device to carry, charge or return. You connect right on your phone the moment you land in Japan.
Yes. Alongside short trips we offer 30-day and Unlimited options, so you can stay connected in Japan on longer stays.
