Updated Map Color Schemes

A major update to the coverage map is coming shortly, but I wanted to release a small, interim update first. With the update released today, the map now defaults to a green-red color scheme for all networks. While the brand-specific colors used previously were kind of fun, I don’t think the meaning of different shades […]

Throttling That Doesn’t Suck

Years ago, some cell carriers introduced “soft caps” for data. Subscribers that used their allotted data could continue accessing the internet at a vastly reduced speed of 128kbps.
