Even though AT&T has plans to release MMS on September 25th, people seem to be chomping at the bit for it, so much so that the good settings wizards over at BenM.at have brewed up a way to enable MMS now, provided that AT&T has upgraded the cell towers in your area. As an FYI for my home town readers, Fresno is one of those cities, so this hack should work for you. It does require just a bit of command line (or Terminal on a Mac) fiddling, so if you’re not comfortable with that, just wait a week for AT&T, but if you are, hit the jump below for the instructions!
Requirements:
- Mac OS X or Windows XP/Vista
- iTunes 9
- iPhone 3G or iPhone 3GS with at least Firmware 3.0
- This AT&T Carrier Settings File
HowTo:
- Close iTunes
- Save the AT&T Carrier Settings File on your Desktop
- Now the methods will change depending on your Operating System
For Mac – Open up Terminal, and at the prompt type defaults write com.apple.iTunes carrier-testing -bool TRUE and hit Enter.
For Windows (32-bit) – Go to Start > Run and type in command, then hit Enter. Then, at the prompt, type “C:Program FilesiTunesiTunes.exe” /setPrefInt carrier-testing 1 and hit Enter.
For Windows (64-bit) – Go to Start > Run and type in command, then hit Enter. Then, at the prompt, type “C:Program Files(x86)iTunesiTunes.exe” /setPrefInt carrier-testing 1 and hit Enter.
- Plug your iPhone into your Mac
- Select your iPhone inside iTunes in the sidebar
- Press and keep the Option-Key hold while clicking on “Check for Update”
- Now select the AT&T Carrier Settings File on your Desktop and hit “Choose”
- Let iTunes install the AT&T Carrier Settings File
- After installing unplug your iPhone and restart your iPhone
- After the restart open the “Settings.app” on your iPhone and go to “General > Network > Cellular Data Network”
- Now enter the following settings
- APN: wap.cingular
- Username: wap@cingulargprs.com
- Password: CINGULAR1 (case sensitive)
- MMSC: http://mmsc.cingular.com
- MMS Proxy: 66.209.11.32
- Press the Homebutton
- Reopen your Settings.app and go to “Messages” and enable MMS Messaging
- Press the Homebutton again and you should be able to send MMS messages now.
This guide only works if AT&T has already updated the cellular towers in your area.

I have the 3GS and i am doing exactly what you are telling me but it does not work. There is not network cellular data on the iphone.
Interesting, it seems to work for most folks. Have you updated to OS 3.1? You must do this for MMS to work properly. AT&T now officially supports MMS as well so you can probably just update to 3.1.2 and the new carrier settings. Let me know if you continue to have problems!

I have OS 3.1.2 and have tried these instructions. I do not have the ‘cellular data network’ option in ‘Settings>General>Network’. Am I doing something wrong? MMS messaging in ‘On’. Can you help?
If you have OS 3.1.2 you should already have MMS, what iPhone model do you have?
