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.

Turn On FDN
  1. Tap the Widget Bar and then tap Settings
  2. Tap Phone Settings > Security
  3. 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.
