If you didn't grant Talkatone access to the Contacts application when you installed Talkatone, information in Contacts will not be visible in Talkatone. You can grant permission manually by following the steps below (See Video Tutorial):
1. Open the Settings app on your i-device.
2. Find "Talkatone"
3. Tap on "Contacts".
4.- Set the on/off button to "On"
Restart Talkatone. You should now see your contacts information from Contacts in Talkatone.
