WAP (Wireless Internet/My Wireless Window)

If you haven't already done so, you must:
1. Get the "Wireless Internet" feature from Cingular
2. Go to My Wireless Window, and register a free account.

Troubleshooting WAP (Wireless Internet/My Wireless Window)

Your AT&T Wireless account must be provisioned (not just enabled) for WAP (and Data Connect) to work properly. When you have an unlocked (unsupported) phone, that can be done in one of two ways:
1. Temporarily put your SIM in a borrowed AT&T Wireless-supported phone with WAP capability (e.g., Sony Ericsson T61z), and have your account enabled automatically, which normally takes only 15 minutes or so. (Once your WAP is provisioned and working, return the SIM to your own phone.)
2. Verify with Customer Service that WAP has been enabled on your account (and Data Connect if desired), and then beg and plead to be transferred to Technical Support. (You might have to lie about having a supported Sony Ericsson T61z that's not working to get there.) Then beg and plead Technical Support to have your WAP provisioned manually. (Good luck -- you'll probably need it!)
If you are repeatedly prompted for User id and Password when you go to My Wireless Window, try the following work-around:
1. MENU: WAP services Clear cache
2. Empty cache?
3. Remove the battery without turning off the phone first.
4. Replace the battery, turn on the phone, and try again.

Data Connect (AT&T Wireless as ISP)

If you haven't already done so, you must have Cingular add Data Connect (also known as "Circuit Switch Data") to "Wireless Internet". Since this uses AT&T Wireless as the ISP, you do not need an account at a standard dial-up ISP.
Setup a Data Account on your phone:
NOTE: A Data Account is necessary only for the email client in the phone. When connecting from an attached device (e.g., notebook computer, PDA, etc.), you do not need a Data Account, since the attached device is responsible for dialing and authentication.
- MENU: Settings Data comm. Data accounts Add account?
- Account type: GSM data
- Name: [enter descriptive name; e.g., "AT&T Wireless ISP"]
- Phone number: 18472549270
- User id: WIDC0001@W4.MYCINGULAR.COM ["0001" is all numeric digits]
- Password: ZXY203DC9K0402 [all "0" are numeric digits]
- Save?
- Press and hold to return to main screen
- MENU: Settings Data comm. Data accounts
- Select Data Account you just created; e.g., "AT&T Wireless ISP"
- Edit
- Dial type: ISDN
- Press and hold to return to main screen
- The following settings are automatically set by default and should normally not be changed:
  - Passwd request: Off
  - Data rate: 9.6 kbits/s [14.4 kbits/s will not work]
  - DNS address: [blank]
The email client in the phone can access email at ordinary ISPs using this Data Account, with the following caveats:
- As a security measure, some ISPs will only allow you to retrieve (POP3) email from their own networks, not from other Internet connections.
- As an anti-spam measure, many ISPs will only allow you to send (SMTP) email from their own networks, not from other Internet connections.
- Older versions of T39 firmware have a bug that prevents sending email unless there is at least one message waiting to be retrieved. If your firmware has this bug, and your mailbox is empty, the workaround is to send yourself a dummy email by SMS.

Data Connect (dial-up ISP)

If you haven't already done so, you must have Cingular add Data Connect (also known as "Circuit Switch Data") to "Wireless Internet". You must also have an account at a standard dial-up ISP.
Setup a Data Account on your phone:
NOTE: A Data Account is necessary only for the email client in the phone. When connecting from an attached device (e.g., notebook computer, PDA, etc.), you do not need a Data Account, since the attached device is responsible for dialing and authentication.
- MENU: Settings Data comm. Data accounts Add account?
- Account type: GSM data
- Name: [enter descriptive name; e.g., "MY ISP"]
- Phone number: [enter phone number of your ISP; e.g., "18005551234"]
- User id: [enter your userid at your dial-up ISP]
- Password: [enter your password at your dial-up ISP]
- Save?
- Press and hold to return to main screen
- The following settings are automatically set by default and should normally not be changed:
  - Passwd request: Off
  - Data rate: 9.6 kbits/s [14.4 kbits/s will not work]
  - Dial type: Analogue [unless your ISP is "ISDN"]
  - DNS address: [blank]

- As a security measure, some ISPs will only allow you to retrieve (POP3) email from their own networks, not from other Internet connections.
