Data Calls

A data call is a call where information, for example, e-mail messages,
is sent between computers or servers via the built-in modem in your
phone. To be able to send and receive data calls, you need:
•

the appropriate computer program, such as an e-mail program.

•

a phone subscription that supports data transmission.

For detailed information, please consult your network operator.
WAP browsing is a data call sent between your phone and a mobile
Internet server, not involving any computer program. See “WAP” on
page 69.

Making Data Calls

Data calls are initiated from the appropriate computer program. To
make data calls you need to connect your phone to a computer via
Bluetooth wireless technology, an infrared port or a cable and then
start the computer program.

Receiving Data Calls

If you have separate numbers for voice and data calls, your phone
recognizes the type of call.

Receiving Data Calls – Separate Numbers
If your network and subscription support separate numbers for the
different types of call, the display shows which type of call you are
receiving.

To receive a data call

1. Connect your phone to the computer.

2. Answer the call from within the computer program (if it is not

answered automatically).

Note:

You cannot answer an incoming data call by pressing the

YES

key on the phone, but you can reject the call by pressing

Receiving Data Calls – One Number
If you have a SIM card that does not support separate voice and data
numbers, the phone does not recognize the type of incoming call.
If you want to receive a voice or data call, you first have to set the
phone to one of these options in the Next incoming sub-menu.
