While you're on a call, you'll hear beeps letting you know another call is coming through.
To answer the call that's waiting you need to either:
- Select flash
- Select recall
- Select the hang up button for half a second
Use the same button to go back to the previous call, or hang up when you're finished on this call.
To disable call waiting, dial *52 before you make a call, or during a call, once you've followed the steps above.
