I have some problem.
When i received a MMS notification of MMS message size over 29KB.

But the size in the notification is 29KB, actually mms message size exceed 29KB.
I heard the size in the notification is mms message size.
but mms download is ok!.
what happen... ? why 29KB ?.

I tested it in uk using vodafone network.
It's UAProf the Max MMS Message size is 300KB.

Hi Sarah,

I had to jog my memory back a few years to recall this issue.

Some early model MMS phones would ignore MMS notifications if the size was larger than the device supported. (And the MMSC could not see the UAProf until after the notification was sent, when the device tried to fetch the content ... but in this case, the device would never try to fetch the content.)

So by default, if "Enable Dynamic Image + Audio Conversion" is enabled in the MMSC, we set the size in the MMS notification to be no higher than 30000 bytes (even if you are sending a notification for an external URL).

To bypass this limit, disable the "Enable Dynamic Image + Audio Conversion" setting on the "MMSC" page of the configuration dialog ... or ... edit MMSC.INI, and under the [MMSC] header, add MMSNotificationHeaderMaxSize=###### to set a higher value for this max than 30000.
