* Comparison of 7-day unlimited plans. Competitor prices surveyed as of July 2026 (Company H has a single worldwide price; Company N is an approximate conversion from JPY). Plans marked with * are “unlimited” with a daily or period-based high-speed cap (FUP). Our unlimited plans (excluding carrier-official plans) have no FUP — completely unlimited at a constant 10–20 Mbps.
* Korea: our plan in this comparison is a stable unlimited type at a constant 10–20 Mbps — priced accordingly. Speeds differ from the full-speed SKT-line plans common elsewhere.
