H2O Wireless vs Smartless Mobile Coverage Map
The map compares native (non-roaming) H2O Wireless and Smartless Mobile coverage across the United States.
Usage
- Zoom close for the most detailed coverage data
- Use the search bar to compare H2O Wireless and Smartless Mobile in a specific location
- Switch view modes to surface different comparisons
- Overlay: Shows distinct coverage areas of each carrier
- Winner: Colors each area by which carrier has better signal or better percent coverage
- Difference: Uses color intensity to show the magnitude of signal or coverage differences
🤓 Technical Notes
-
Real-world relevance: When comparing H2O Wireless and Smartless Mobile signal strength,
the map's difference view uses predicted RSRP values but colors hexagons based on expected real-world impact. A difference between -125 dBm
and -100 dBm (poor to fair) has greater visual impact than a difference between -90 dBm and -65 dBm (excellent to especially excellent).
-
Metrics with high zoom: Zoom in for the most detailed picture. At the highest zoom levels (smallest hexagons),
the Winner and Difference views show signal strength comparisons between H2O Wireless and Smartless Mobile.
-
Metrics with low zoom: When zoomed out (larger hexagons), comparisons are generally based on
coverage percentage within each hex. Signal strength is only compared when both H2O Wireless and
Smartless Mobile have 100% coverage of a hex. ⓘ
Data Sourcing
Cell coverage data for H2O Wireless and Smartless Mobile comes largely from the May 2025 release of the FCC's Broadband Data Collection program
(representing networks as of December 2024) with supplementation from massive crowdsourcing efforts.
