A wireless communications device includes a radiofrequency transceiver having a wireless voice channel for transmitting and receiving voice communications and a separate wireless data channel for concurrently transmitting and receiving other data. The wireless communications device also includes a memory operatively connected to a processor for processing current location data received over the data channel from another communications device with which the wireless communications device is simultaneously communicating on the voice channel. The wireless communications further includes a display for displaying a phone screen during a voice call, the phone screen presenting call-related information. A map is displayed on the phone screen during the voice call, the map presenting a location current of the other communications device based on the current location data received over the data channel. Optionally, the map can also show the current location of the wireless communications device.
