Nokia Lumia 820 - How do I use call waiting on my Lumia phone?

If supported by your service provider, call waiting notifies you of an incoming call even while you are in a call. You can accept, reject, or ignore the incoming call.

On the Start screen, select Phone.

  • To enable the call waiting feature on your phone, type *43# in the dialer and press call.
  • To disable it, simply type #43# in the dialer and press call.
  • You can see whether call waiting is active, and for which type of calls. Type *#43# in the dialer and press call.

Note: Call settings do not work on 4G. To switch the call waiting option, change the Highest connection speed, go to Settings > Cellular.
