Google is going to be a wireless provider just like AT&T, Verizon, and T-Mobile. 

Well, maybe not just like those big companies. 

At the industry trade show Mobile World Congress, Google executive Sundar Pichai said the company would do its own wireless service at a "small scale" to "show what's possible." 

Google is going to be a mobile virtual network operator (MVNO). An MVNO buys wireless spectrum from someone else, like AT&T, and then rebrands/repackages the service for users. 

Pichai is framing Google's wireless plan as an experiment along the lines of what Google did with the Nexus phones. It wants to show bigger wireless carriers what is possible. 

So initially this will not be a big product. But if it works, we could see Google expanding it over time. 

Here are tweets from Amir Efrati, a reporter at The Information, who live-tweeted Pichai's talking about Google's MVNO:
