What are the TCP and APN settings?

Setup the APN by going to Options >> Advanced Options >> TCP and enter the following information based on your carrier. A special thanks to Mark Rejhon @ BlackBerry Forums

Rogers

APN: internet.com

Username: (blank)

Password: (blank)

Note: If this does not work, call Rogers and get the “internet.com Access Point Name” added to your account. If they say it already exists, tell them to load up the records anyway, just to doublecheck.
T-Mobile

APN: wap.voicestream.com

Username: (blank)

Password: (blank)

Note: T-Mobile has fixed the port-blocking issue – see this post for more info. In rare cases, it is reported you may need to enter your T-Mobile username and password, the same information used for logging into www.t-mobile.com/bwc … If it still does not work properly, just call T-Mobile (call after Feburary 11th, 2005), and ask them to get the “wap.voicestream.com Internet Access Point Name” added to your BlackBerry account at no extra charge.’
Cingular Orange

APN: WAP.CINGULAR

Username: WAP@CINGULAR.COM –or– WAP@CINGULARGPRS.COM (<—try one then the other)

Password: CINGULAR1

Formerly, it used to be difficult to get this to work on Cingular but in December 2005, a new Internet Browser Icon suddenly appeared on Cingular BlackBerry units. When this happened, it also suddenly became easier to use Cingular BlackBerry with TCP/IP. If you are still having problems, please click here.
Cingular Blue

APN: proxy

Username: (blank)

Password: (blank)

Try using these settings if you are on the former AT&T network, instead of the Cingular settings.
Orange UK

APN settings should be enabled.

APN authentication box should be checked.

APN: orangeinternet

Username: user

Password: pass
