I have had a few requests for how to get GPRS and WAP running on the XDA II when used with the AT&T Wireless service. I plan on a full review of the XDA II in a few weeks, but I know many of you need this info sooner than later so here are the details so far:
|
In Windows Mobile 2003 Phone Edition you can switch the GPRS Setting method you use when you make a GPRS connection.
In the GPRS setting utility there are two choices to select from. The first choice is PAP authentication. PAP stands for Password Authentication Protocol. This is a less sophisticated authentication process that uses clear text passwords.
The second choice is CHAP authentication. CHAP stands for Challenge Handshake Authentication Protocol. CHAP negotiates a secure form of encrypted authentication between the server and the client.
AT&T wireless used CHAP authentication for connecting to the internet via GPRS.
Windows Mobile 2003 has a simplified wizard for setting up your connection that eliminates a lot of the guess work that existed in the previous version. You can use the wizard to configure and connect your XDA II to the internet for web and WAP browsing.
In this tutorial I will be using the i-Mate from www.Expansys.us with an AT&T Wireless SIM chip installed.
Configure GPRS Access on the AT&T Wireless Network
 
1 Tap Start
2 Tap Settings
3 Tap Connections
4 Tap GPRS Setting
5 Select the CHAP authentication radio button
6 Optional: Tap the GPRS – Setting tab
* Select the time slot you wish to use:
Class 8 (4R1T) indicates 4 receive slots and 1 transmit slot
Class 10 (3R2T) indicates 3 receive slots and 2 transmit slots
If your primary use is to download content from the internet, email, and other data heavy information Class 8 will provide you with better performance. Class 10 takes away 1 of the receive slots and gives you an extra transmit slot, this will be helpful if you send a lot of email, MMS pictures, transmission of large files or data.
7 Tap OK
* Your device is now ready to make connections.
Configure Device for Internet Web Browsing
1 Tap Connections
2 Under My ISP, select “Add a new modem connection”
3 Enter a name for your connection; I used “GPRS Connection”
4 From the Select a modem drop down box choose Cellular Line (GPRS)
5 Tap Next
6 In the text box labeled “Access point name” type in “proxy” with out the quotes
7 Tap Next
8 Leave the User name, Password, and Domain fields blank
9 Tap Finish
10 Tap OK
* Your device is now ready to browse the internet.
 
Configure Device for WAP Access
1 Under My Work Network, select “Add a new modem connection”
2 Enter a name for your connection; I used “WAP”
3 From the Select a modem drop down choose Cellular Line (GPRS)
4 Tap Next
5 In the text box labeled “Access point name” type in “proxy” with out the quotes
6 Tap Next
7 Leave the User name, Password, and Domain fields blank
8 Tap Finish
9 Tap the Proxy Settings tab
10 Place a check in both boxes
11 Leave “Proxy server” blank
12 Tap Advanced
13 Leave HTTP and Socks Server fields blank.
14 Enter 10.250.250.250 for your WAP server. Ensure your port number is 9201
15 Enter 10.250.250.250 for your Secure WAP server. Ensure your port number is 9203
16 Tap OK twice
* Your device is now ready to browse WAP sites. To view the AT&T Wireless WAP site enter wsp://home in the address bar in Internet Explorer.
 
You XDAII will now switch between WAP sites and Internet sites on the fly. The connection change takes only a few seconds. Windows Mobile Phone Edition does not have an intuitive way to disconnect your GPRS connection. To manually disconnect you can depress the “end call” button on the device for a couple of seconds and that will end your GPRS session.
Additionally you can start a GPRS connection by accessing an application that uses the internet like internet explorer or by tapping the radio icon on the today screen and selecting your GPRS connection type.
That's it for now, I will make changes as needed to this tutorial. If you use another wireless carrier and would like to share your connection settings we will be happy to post them to help our non AT&T Wireless readers.
