Google will unveil its much rumoured mobile network service later on today, according to a new report.
There have been murmurs that Google was intending to become a Mobile Virtual Network Operator (MVNO) dating back to November, and Sundar Pichai confirmed those murmurs to be true at MWC 2015.
While identified as Project Fi at present, it could be called Google Wireless at launch.
Now the Wall Street Journal is reporting that Google is preparing to launch that virtual mobile network in the US today, April 22.
The key feature of Google's mobile network will be that its users pay only for the data that they actually use each month. Typically, users in the US (just as in the UK) pay a fixed price for a set amount of data, which then essentially resets at the beginning of the next month.
Another feature of Google's network is the close integration of Wi-Fi calling to further reduce a subscriber's phone bill.
While Google's Sundar Pichai has said in recent months that this is little more than a small scale experiment, the new approach is bound to be worrying the major US networks stuck in a familiar way of doing things.

In this way, it could prove to be similar to Google Fiber, which has prompted change amongst US broadband providers despite only being available in only a few cities.
