Using The Flash Function - Nokia 252 252 Owner's Manual

Using the Flash Function

Your cellular system may offer a flash function service. This sys-
tem service lets you accept or make a second call when you
already have a call in progress (e.g. set up a conference call), or
send other information to the network, such as credit card
numbers.


Pressing sends a displayed number to the network as a
flash, unless it is preceded by a 'p' or 'w'. (In these cases it is
sent as a Touch Tone.)
After the phone number has been entered, you can add extra
information which is for 'flash' sending to the network.
Contact your service provider for further details.
