A free program for Android, by AndroidSTT.
For those of you who want to transfer your calls to another number without having to re-enter the phone number, you can use Forward My Calls. The application saves the last number you used to make the call simpler for the next time. You can easily remove the banner ad and use the application for free.
You can use the application for free if you are an existing customer of one of the three carriers (T-Mobile, AT&T, and Verizon) that provide mobile phone service in the U.S.A. If you are not an existing customer, you can easily purchase the service for a fixed monthly fee.
