If you are on AT&T and own an iPhone, you might have surely activated MMS last week when AT&T finally allow MMS on iPhone. But there seem to be quite a number of users who are still not able to send MMS – check this topic MMS message send failure. CNET has shared this simple solution. Try it out and let me know if this works:
- All your preferences and settings are reset. Information, such as your contacts and calendars, and media, such as your songs and videos, aren’t deleted.
- You will have to re-enter your passcode, Wi-Fi passwords, and your apps will all be rearranged alphabetically. Note: the latter issue is actually a neat find–now I know how to alphabetize my apps when I want them sorted that way. Drastic yet effective.
- Additionally other settings like VPN, remembered Wi-Fi networks, etc., maybe lost.
Fixing the MMS send failure error message
- Connect your iPhone 3G or 3GS to your computer.
- Launch iTunes and go to the Summary tab for your iPhone.
- Click the Restore button to restore your iPhone and allow it to use your most recent backup when prompted; iTunes should do this automatically. This process will take a while so it is recommended that you try it only when it is convenient and you are not in a hurry. Once it is completed your iPhone will reboot.
- Launch Settings on your iPhone.
- Go to General > Reset All Settings > enter your PIN if prompted
- Try sending and receiving an MMS now.
