In March, Google confirmed its plan to launch some sort of wireless service for consumers in the U.S., and a new report claims that the Internet biggie could pull back the curtain on this new product as early as today.

This is according to the Wall Street Journal, which reports that a major difference between existing wireless providers and what Google intends to provide is that customers would only pay for the data they use each month.

So rather than wasting money on unused data each month, your bill would reflect your actual usage. Whether that ultimately saves you money will depend on how much Google charges.

As mentioned in earlier reports, it’s expected that Google’s service will run on existing Sprint and T-Mobile networks. It may also use WiFi hotspots to carry phone and data signals, reducing the burden on the wireless system.

The biggest drawback, according to the Journal report, is that the Google service will only work — at first — for users with Google Nexus 6 devices. So consumers with the most popular smartphones — like Apple’s iPhones and Samsung’s Galaxy devices — would have to switch or wait until Google supports their phones.
