The only bad cell company is Sprint

The report comes from OpenSignal, a company that persuades users to download an app, which then quietly runs speed tests in the background. It has billions of data points from hundreds of thousands of users, and as such provides the best picture of network coverage, quality and speed. […] Verizon wins availability by a hair: its subscribers have a 4G signal 86% of the time, T-Mobile 83%, and AT&T 80%. Sprint? 69%. (Lol.) For speed, T-Mobile actually wins, at an average download of 16Mbps. Verizon and AT&T are both in the double digits, while Sprint finishes in last with 9Mbps. Seeing a trend here? – Chris Mills, BGR
