Android phones can forward only the calls you miss, from the Phone app menu or with your carrier's code. Your phone rings first, and missed calls go to your TextbackFast number.

AT&T shows these menus in its Android device guides (AT&T device support). Menu names vary by phone maker and carrier. Some carriers, such as Verizon, do not show this menu, so use the code instead.
