Error 678: There Is No Answer

If you have previously established connections successfully using the same

wireless device and network profile, the problem is most likely that the

device that answers your data call is temporarily out of service. This is a

network problem. It will most likely be addressed by your provider shortly.

Select a different profile to connect or try again later.

Other possible causes include the following:

• The wrong telephone number is being dialed. Verify that the Dialed

Number field of the network profile you are using to connect contains

the correct number See

How to Edit a Network Profile for more

information.

• There may be a problem with your cellular device's firmware. Verify

that your device is using the latest version of operating software offered

by its manufacturer. If you have an alternate method of connecting to

the Internet, you can find links to the latest firmware for many devices

on Cingular's

laptop support web page.

Error 679: Cannot Detect a Carrier

This error usually has one of the following causes:

• You are not using the correct network profile to establish the connection

or the profile you are using is not configured correctly. Try selecting an

alternate connection profile from the Select GSM Connection Profile

section of the Connections menu or check with your IT administrator to

see if you have a custom APN for connecting to the Cingular network.

• The network profile you are using to establish the connection has an

incorrect dialed number or access point name (APN). Verify the

contents of these fields. See

How to Edit a Network Profile for more

information.

• The Subscriber Identity Module (SIM) in your cellular device has not

been properly setup or has not been configured for data service.
