An exemplary wireless device includes a communication radio and a position location receiver. When the wireless device has established a call with the communication radio, and a request for position location is received, the communication radio is deactivated while the position location information is collected using the position location receiver. A local warning message is communicated to the user of the mobile device while the communication radio is disabled. The warning message may be a text display, a graphical display, an audio message, or an input-key challenge. By generating and presenting the local warning message, the user is made aware that the lack of normal call activity is expected and temporary. After the position location information is collected, the call is resumed with the communication radio, and the position location information is transmitted. Since the mobile device is now acting with normal call activity, the local warning is removed.
