Hi compaq0. My name is Straight Talk Lindsay. From the main screen, press and hold the Search key to access Voice Commands. You may clearly say Call [Name or Number] as it is saved in your Contact List. Note: If there are multiple numbers for a Contact (e.g. work, home, or cell), then say the name and number location. Note: You may need to tap the Contact if the number is not dialed automatically. To end the call, tap the End icon. Thanks.
