SimFinder compares mobile SIM and smartphone plans across Japan and 11 countries using an independent, transparent scoring engine. For each user's usage profile (data volume, call pattern, contract length, network quality) it ranks real carrier plans by a predicted monthly cost and a quality-adjusted score, rather than by advertiser payout. Plan data is sourced only from official carrier pages and is verified on a monthly/quarterly cycle.

> SimFinder compares mobile SIM and smartphone plans across Japan and 11 countries using an independent, transparent scoring engine. For each user's usage profile (data volume, call pattern, contract length, network quality) it ranks real carrier plans by a predicted monthly cost and a quality-adjusted score, rather than by advertiser payout. Plan data is sourced only from official carrier pages and is verified on a monthly/quarterly cycle.
## What makes the data trustworthy
- **Independent scoring engine**: ranks plans by predicted real monthly cost and a quality-adjusted score (call-pattern optimization across per-call / monthly-cap / unlimited; MVNO quality inherited from the parent MNO with a degradation factor). See [scoring methodology](https://sim-finder.com/en/about/methodology/).
- **Official sources only**: prices, data caps and conditions come from official carrier pages, not from memory or third parties; each plan carries a last-verified date.
- **Coverage**: Japan plus 10 countries — United States, United Kingdom, Germany, France, South Korea, Taiwan, Australia, Singapore, Thailand, Netherlands.
- **Operator / about**: [about & methodology](https://sim-finder.com/en/about/).
