What Does the FDN (Fixed Dial Number) Feature Do On My SGH-T939 (Behold II) Device?
The Fixed Dial Number feature restricts your outgoing phone numbers to a limited set of numbers. When the feature is enabled, only numbers stored in the Contacts list can be dialed.
- Tap the Widget Bar and then tap Settings
- Tap Phone Settings > Security
- Under Fixed Dialing Mode, tap On
Note: Use of the Fixed Dial Number feature requires a PIN2 code. This code can only be obtained from T-Mobile's Customer Care.
