Verizon and AT&T plan to switch on cross-network VoLTE calls in 2015, the two carriers have confirmed today, opening the door to first voice over LTE calls and then one day video calling and messaging. VoLTE launched on Verizon's network in September, allowing handsets like the iPhone 6 to use the data network for VoIP rather than traditional methods, with the addition of HD-quality audio too.

Test-driving OnStar 4G LTE: Geek-heaven or Gimmick?

GM has been talking about baking 4G LTE into its cars for some time, but the first examples are just now rolling off the production line and into dealerships. Upgrading OnStar with a 100x faster data connection, it adds support for mobile hotspot sharing, remote control by smartphone and smartwatch, and third-party apps and services.

Which is the fastest US network? It’s complicated

Smartphones and tablets are faster and more capable than ever, but without a similarly speedy internet connection - usually LTE - they're still hamstrung. Unfortunately carrier maps are generally more interested in breadth of coverage than quality, hence third-party testing has stepped in to help answer the question of "Which US carrier is the best?"
