as the title says I have iMessage on and SMS on but can't send or receive regular or mms messages only iMessages go through. I already reset network settings turned on ad off iMessage I even did a hard reset still nothing.
I only explain how my situation was solve. It may help others.I sold my 4s the sim is sitting in my closet lol
NP, I was very frustrated because of the same situation and magically, after I resorted my iPhone 4S from my last backup and then removed the SIM Card the problem was solved : )I appreciate the input but this problem is happening on my other line which has a 4s on ios6 also.
I downloaded ibackupbot. When I tried to edit that file, the software said I have to purchase a full version of ibackupbot, which costs $35. Help me out here...100% fix:
it takes a little iPhone know how, but works 100%. When the phone comes from one carrier to another the c0m Apple mms_override.plist file isn't changed when restored from backup, even if you reset the network settings, so what you need to do is edit this file.
in iTunes make a backup of your phone
Download ibackupbot to edit your back up
find the file com Apple mms_override.plist
edit this file to look like this:
(it won't let me put in the first two lines of code because there is a web link in them, so leave the first two lines that are in the file)
<plist version="1.0">
<dict>
<key>MMS</key>
<dict/>
</dict>
</plist>
click the little disk icon to save your changes, and then quit ibackupbot
open iTunes, and restore from your backup
TA FREAKIN DA!
