We got unlimited mobile to mobile family messaging package (included SMS and MMS), but I had trouble sending or receiving MMS when I tried it out. I found a solution....
1. Make sure "wap.cingular" is configured as the "Access point name." (It MUST!!)
* Additional features such as Wi-Fi and device based e-mail along with other 3rd party applications may not be compatible with the proxy settings associated with the MEdia Net profile.
* If there are connection issues with e-mail and/or Wi-Fi, configuring and using the My ISP profile as displayed below may resolve connectivity issues.
* Configuring the AT&T 8525 to use My ISP will disable MEdia Net (WAP) web pages when My ISP is used for connectivity. However, regular Internet (HTML) web page browsing will function as normal.
For those using Media.net

For those not using Media.net, but using "My ISP" (Configure the Connection Settings to Bypass the AT&T proxy on the AT&T 8525 )

2. Configure MMS Settings for the AT&T 8525

If you follow the instructions, MMS will work!!
