Outgoing Cell Calls Experience a Busy Signal (Samsung)


  • Outgoing cell calls result in a busy signal
  • Can receive calls on the cellular network



  1. Open the Phone app
  2. Tap the 3 stacked dots in the upper-right
  3. Tap Settings
  4. Scroll down and tap Supplementary services
  5. Tap Show my caller ID

If you don't have this set to Network Default, our GSM cellular partners can't see what number is being used to place the call and aren't able to route the call correctly
