The fine print, finally decoded.
We read every carrier contract, ran every speed test, and mapped every dead zone — so you don't have to make a $1,200/year mistake at midnight.
Carrier Comparison Guides
Each guide is a full field investigation — not a spec comparison. We activate the plans, run the tests, and read the contracts so the verdict is earned.
The 2025 Family Plan Showdown: 4 Lines, Two Bills, One Winner
We activated identical family plans on both networks for 90 days across Phoenix, rural Montana, and downtown Chicago. The price difference at renewal was $47/month — but not the carrier you expect.
Starlink vs T-Mobile Home Internet: A Rural Remote Worker's 6-Month Log
Video calls dropped 11 times in one week on T-Mobile Home Internet in central Nebraska. Then we switched. Latency figures, upload consistency during peak hours, and the actual cost per reliable megabit.
Can 5G Fixed Wireless Replace Fiber for a Small Business? We Found Out.
A 12-person agency in Austin ran Verizon 5G Home as their primary connection for 60 days. Peak-hour throttling kicked in at day 18. Here's the exact usage threshold, the fallback plan, and whether the $30 monthly savings is worth the risk.
Speed Test Data
2,847 tests run across 14 states over 4 months. Median download speeds in Mbps — not the cherry-picked numbers carriers use in ads.
Median Download Speed — Urban Environments
Mbps · Q4 2024 – Q1 2025 · n=2,847
Urban outlier: 680 Mbps on mmWave in Manhattan
Rural outlier: 9 Mbps in eastern Montana
Best rural consistency of the three carriers
Outlier: latency spikes to 800ms during rain fade
No rural coverage — urban speeds are consistent
● Filled circles indicate outlier data points. Hover bars for context notes. Rural column shows 0 for Comcast — no coverage in tested areas.

Coverage Horror Stories
Submitted by Signal readers. Edited for clarity, verified where possible. These aren't edge cases — they're the fine print working exactly as designed.
Verizon promised 5G. The tower is 12 miles away.
I work from home. Verizon's coverage map showed a solid 5G signal at my address. After 3 months of 1.2 Mbps video calls, I found out the nearest tower is 12 miles east. The map uses "extended range" 5G — which is just rebranded 4G at full price.

T-Mobile throttled our family plan at day 22 of 30.
Our "Unlimited" plan throttled video streaming to 480p on day 22. T-Mobile's fine print defines "unlimited" as unlimited at reduced speeds after 50GB. We used 51GB. Four kids, two parents, one month of blurry homework videos.

Starlink saved our veterinary practice.
Our rural clinic relied on a DSL line that dropped during any weather. We switched to Starlink in March 2024. Upload speeds went from 0.8 Mbps to 22 Mbps. We can now run telemedicine consultations and upload X-rays without scheduling around weather windows.

AT&T's "fiber" turned out to be fiber to the curb.
AT&T advertised 1 Gbps fiber at my address. The technician arrived and installed VDSL from a box at the curb — copper wire runs the last 400 feet to my house. Maximum speed: 80 Mbps. They still call it fiber in the invoice.

Charter Spectrum charged us for a modem we returned.
Returned the modem in person with a receipt. Two years later, I found a $14/month equipment fee that had been silently added back. Total: $336 billed for equipment I haven't owned since 2022. Dispute took 11 calls.

Comcast raised our rate $22/month with a notice buried in spam.
The price increase notification arrived in an email titled "Your Xfinity account update." It looked like a receipt. The $22/month increase to $89 was in paragraph 4. We caught it 4 months later — $88 already billed.
