Price source, availability & value labels
Supplier catalog source ↗ (opens in a new tab) · checked 2026-11-01T23:16:18.076Z. These are dated reference prices from the published catalog, not live quotes. They expire after 24 hours. Confirm the final price before paying. Roamly adds no extra fee.
“Best Value” means the lowest price per GB among fixed 30-day plans with the same listed networks and conditions. Plans with pricing issues, missing data, or expired evidence are excluded. No value label is shown for destinations with unresolved pricing inconsistencies.
Data only. Hotspot uses your allowance. Check the exact activation rule and coverage before buying. Coverage & networks ↗ (opens in a new tab).
A note for your journey.
Download your maps and travel documents before you fly. For a route that continues beyond Japan, compare the exact country list of a regional package.
Traveling further?
Compare the Asia Pacific regional guide. Confirm that this country is included; geographic proximity is not proof of package coverage.
Good to know before buying.
Use a compatible, carrier-unlocked phone. The plans provide mobile data, without a new phone number. Read supplier terms and refund conditions ↗ (opens in a new tab) before payment.
