FAQs

Octopus Japan eSIM - Common Questions

Most phones from the last few years support eSIM - including iPhone XS and newer, Pixel 3 and newer, and most recent Samsung Galaxy flagships. Open your phone's cellular settings and look for "Add eSIM" or "Add Cellular Plan" to confirm.
Install it before you fly, while you're still connected to Wi-Fi. First-time eSIM activation requires an internet connection. You can keep it toggled off until you land.
Coverage varies by plan. Each eSIM product page lists the supported countries and the carriers used in each region. If a country isn't listed, the eSIM won't connect there.
These are data-only eSIMs. You can still use messaging apps (WhatsApp, iMessage, Telegram) and VoIP calls over the data connection. For traditional calls and SMS, keep your home SIM active in parallel.
You can purchase a new Octopus eSIM top-up at any time. Your device keeps the installed profile - you just activate a fresh data bundle on it.
Each QR code is single-use and tied to a single device once installed. If you change phones mid-trip, contact support at hello@octopuscards.io and we'll help re-issue the profile.
Yes. The card itself is valid for 6 months from purchase. Once you activate the eSIM, the data plan's own validity window (usually 7, 15, or 30 days) begins.
