Google

Back in January, we learned that Google was plotting to launch its own brand of carrier, and while it wouldn't be building the infrastructure up from scratch, its pricing models would throw down the gauntlet to current providers. Since Google already manages the most ubiquitous smartphone platform of them all - Android - it's a move that doesn't come as too much of a surprise, and now, we're learning that it could be ready for prime time in a matter of weeks. Initially, it'll only launch on the company's Motorola-built Nexus 6 smartphone, and although there's no word on when or indeed if the network will support further handsets in the short-term, it's likely that Google will expand pending a successful introduction.
