How Do I Use Call Waiting On My Helio SPH-A523 (Mysto)?
While on a call you will hear a tone when another call is coming in. Press the green talk button to place the first call on hold and answer the second call. To return to the original call press the talk button again; this will place the second call on hold.
Note: Call waiting service must be enabled on your account with your service provider to take advantage of this functionality on the Helio SPH-A523 (Mysto) handset. Please consult with your provider for information regarding any additional fees that may be incurred.
Tip: For those calls where you don’t want to be interrupted, you can temporarily disable Call Waiting by pressing *70 before placing your call. Call Waiting is automatically reactivated once you end the call.
