Google has begun testing a phone number portability add-on to its Voice service, allowing a select band of users to switch over to Google Voice for $20.
The service is designed to provide all users' phone lines with a central Google Voice number. Once the process is completed, whenever the Voice number is called, every phone connected to it will ring until one is answered.
The feature allows users to terminate their contract with their existing carriers and rout all their calls from a central Google Voice number.
One downside of cancelling an existing mobile contract is that users might end up paying an early termination fee to their carrier.
The company said in a statement to Engadget: “We're continually testing new features to enhance the user experience. For a limited amount of time, we're making the Google Voice number porting process available to users. We don't have any additional details to share at this time, but plan to offer this feature to all users in the near future.”
