If you use your phone mainly on Wi-Fi at home and only use 1–5GB of cellular data per month, you are massively overpaying for an unlimited plan. Mint Mobile's 5GB plan at $15/month or Google Fi Flexible at $20/month + $10/GB are designed exactly for you — and could save you $540–600/year vs Verizon.
Check your phone: iPhone → Settings → Cellular → Cellular Data Usage | Android → Settings → Network → Mobile Data Usage. The average US smartphone user uses about 8GB/month, but Wi-Fi-first users at home and the office can easily stay under 3–5GB on cellular.
| Plan | Network | Monthly | Annual | Data | Notes |
|---|---|---|---|---|---|
| Mint Mobile 5GB ★ Best value | T-Mobile | $15 | $180 | 5GB high-speed | 12-month prepay. Best price anywhere. |
| Google Fi Flexible | T-Mobile + USC | $20 + $10/GB | $240–360 | Pay per GB used | Best for variable users. International included. |
| Mint Mobile 3-month plan | T-Mobile | $20 | $240 | 5GB high-speed | Pay quarterly, not annually. Good trial option. |
| Consumer Cellular Basic | AT&T + T-Mobile | $20 | $240 | 250MB (upgrade as needed) | US-based support. Best for seniors or tech novices. |
Most unlimited plans cost $25–65/month. If you regularly use under 5GB, you are paying for data you will never use. A 5GB plan at $15/month gives you everything you actually need.
| Activity | Data used | Monthly estimate (daily use) |
|---|---|---|
| Social media browsing | ~150MB/hour | ~1–2GB |
| Music streaming (Spotify) | ~150MB/hour | ~0.5–1GB |
| Standard video calls (FaceTime) | ~350MB/hour | ~1–2GB (30 min/day) |
| Maps/navigation | ~5MB/hour | ~0.2GB |
| Email and messaging | Very low | ~0.1GB |
Total for a typical light user spending most time on Wi-Fi: 2–4GB/month on cellular. A 5GB plan covers this with headroom.
