We've been watching the latest commercial for Verizon LTE "hiking" claiming that the network is "astonishing." MetroPCS calls its data 4G LTE. While AT&T does not advertise its speed. Which is really the fastest? What do real speed tests show? Which is the best for you? (video follows).
OpenSignal has an app that shows download and upload speeds. We ran tests indoors with a Samsung Galaxy S III on the AT&T network and Droid RAZR MAXX HD on the Verizon 4G LTE network along with a standard dual-core Motorola Atrix using a Wi-Fi connection.
