This is insane. I can't think of an industry that google is not trying to compete in. Auto industry, space industry, internet of things industry (Nest), internet/media industry, cable/internet provider industry, automobile industry, robotics industry, software industry, smartphone industry, pc industry now the telecom industry. I'm starting to expect Google to launch an airline here pretty soon. How can they possibly…
Auto industry? I'm assuming you mean self driving cars, which, at this point, are still in the concept phase. Space industry? Did I miss something, is Google launching rockets?
There are many other companies that are way more diversified than Google.

Plus, expanding into a wireless carrier makes way more sense for Google than any of their other ventures. One of the limiting factors of internet use in the first-world is terrible carriers with data caps.
