Problem

When adults in their 50s review their parents' (60s–70s) phone bills, it's common to find them paying for 30GB data plans while actually using only 3–5GB. Switching to an MVNO could save $22–$37/month (3–5만원), but checking usage under the parent's name, comparing plans, and handling the number transfer takes 3–4 hours—and with 50+ MVNO providers, comparison alone is overwhelming.

Solution

Users enter their parent's current carrier, plan, and monthly usage (data/calls/texts) on the web. The system compares plans across all carriers including 50+ MVNOs and recommends the top 5 by monthly savings. Includes a number transfer step-by-step guide and a power-of-attorney form for when children handle the switch. Features a 'Show to Parents' mode (large text, essentials only).

Target: Ages 45–55, managing phone plans for parents aged 60+, combined parental phone bills exceeding $75/month (월 10만원+)
Revenue Model: Plan comparison free; MVNO sign-up referral commission $2.25–$3.75 per transaction (3,000–5,000원); number transfer concierge service $7.50 Per Transaction (9,900원)
Ecosystem Role: Education
