You can sign up for Google Voice and use many of our features for free including making calls to the US and Canada. The section below explains how using Google Voice on your cell phone may impact your cell phone bill.
Google Voice on your mobile phone
Making domestic calls
When you use Google Voice on your mobile phone, domestic calls will use the standard minutes from your cell phone plan.
Each time you place a call, instead of dialing the number you want to reach, Google Voice dials a US-based direct access number. The Google Voice server then forwards your call to the actual destination number. This allows for faster call setup and the ability to place calls without a data connection. These direct access numbers may show in your phone's call log, or on your phone bill.
A unique direct access phone number is assigned to each person that you call. The direct access numbers are stored in the Google Voice application, not in your Contacts. They can be purged from your phone at any time by signing out of the Google Voice app.
Making international calls
When you use Google Voice on your mobile phone, international calls use the standard minutes from your cell phone plan and are charged against your Google Voice credit, at Google Voice international rates. International calls are also placed through direct access numbers, as described above.
If you have a US based phone number, and try to place calls via Google Voice while you are in another country, you will be charged the Google Voice international rates, and may also be subject to additional roaming fees from your carrier.
Sending and receiving text messages
When you use Google Voice on your mobile phone, text messages are sent through your data plan, as opposed to your text messaging plan, so there won't be any text messaging charges for messages that you send to numbers in the US or Canada.
Note: If you have your mobile phone listed as one of your forwarding phones in your Google Voice account, replies will come to the Google Voice app, but will also be duplicated in the Android Messaging app. Depending on your carrier, you may be charged for your received text messages. To disable this and only have messages sent to the Google Voice app, sign in at voice.google.com, then go to Settings > Voice settings > Phones > (your mobile number) > Edit > Receive text messages on this phone > Uncheck and Save.
