Your phone stores the numbers of incoming
Sprint PCS Wireless Web Connection calls with your voice
Caller IDs. To let you know which is which, you will see
"Data" or "Fax" along with the number of the caller when
viewing your Caller IDs.
While connected on a Sprint PCS Wireless Web Connection
call, you can still access most features. You can navigate the
phone's menu system to change or view your phone's
features or Phone Book entries or read messages or Caller IDs
that you received before placing the call.
If someone tries to reach you during a
Sprint PCS Wireless Web Connection call, you phone will
behave like it is turned OFF (depending on your service,
callers will probably get your voicemail). If you subscribe to
Call Waiting, it will automatically be deactivated whenever
you place or receive a Sprint PCS Wireless Web Connection
Call.
When you have an incoming Wireless Web connection call,
your phone's display will show what type of call you are
receiving, along with the number of the caller. If the number
matches an entry in your Internal Phone Book, the name will
also be displayed.
If you select Auto Answer mode, your phone will
automatically answer Sprint PCS Wireless Web connection
calls when the data cable is connected.
