02 / HOW TO READ THIS
Choose with the limits visible.
- Prices in JPY, USD and EUR are displayed side by side without conversion or cross-currency ranking.
- “Unlimited” does not mean unthrottled; an unconfirmed FUP excludes that plan from allowance-based recommendations.
- 5G and network wording remains qualified where destination evidence is incomplete.
- Dynamic discounts, coupons and credits are separate from the regular price and never drive the matcher.
- “Data only” refers to regular carrier calls and SMS on the selected plan; internet calling apps and separately purchased add-ons are different services.
