Google is reportedly set to unveil its anticipated wireless service 'as early as Wednesday,' April 22.

According to a report out of The Wall Street Journal today, Google will debut a wireless offering as soon as April 22 that will let customers pay for only the data they use, as opposed to purchasing large blocks of data that may go unused. WSJ reports:

Google Inc. is set to unveil its new U.S. wireless service as early as Wednesday, pushing the Internet giant further into telecom and injecting fresh uncertainty into a wireless industry already locked in a price war.

In a key development, the service is expected to allow customers to pay only for the amount of data they actually use each month, people familiar with the matter said—a move that could further push carriers to do away with lucrative "breakage."

Additionally, the report claims that Google's wireless offering will operate on both the Sprint and T-Mobile networks — switching between whichever has the best connection at any given time — and will, at least initially, only work with Nexus 6 devices. Hoping to limit the amount of actual mobile data used, it's speculated that the service will lean on Wifi whenever possible as well.

Google's Sundar Pichai first mentioned the company's plans for a wireless service that would leverage Wifi to bolster cellular service earlier this year at Mobile World Congress. However, he stressed at that time that any MVNO offering would be limited in scope. That aligns with the WSJ report, which indicates that Google agreed to terms with a reluctant Sprint that would let the companies restructure the relationship for their service if they grew too much.

In other words, Google isn't looking to compete with the "big four" with its planned service. In any event, if this latest report holds up, we should hear much more on Google's plans relatively soon.
