Speculation about MMS fault

Since 2006, CMCC-AH-TC MMS fault constantly.

Many terminals with normal settings and normal GPRS functions cannot accept MMS messages!

The situation is summarized as follows:

1. This fault occurs frequently on machines of older models and small brands, such as some domestic mobile phones, cect, top, and Samsung old models.
2. MMS can be used normally on these machines before.
3. None of the currently known solutions can make it normal
4. Other GPRS functions are not affected. Most mobile phones can send but cannot receive (content cannot be downloaded)

Fault prediction:

The MMS center no longer supports these types of mobile phones, or the support is faulty, resulting in the failure to send MMS messages.

Consequence:

1. When users seek help in the business office, the staff spend a lot of time debugging but cannot solve the problem, resulting in a decrease in satisfaction.
2. An error occurred while receiving the MMS Message. The resulting GPRS traffic fee cannot be reduced, causing a complaint.
3. Affected GPRS Service Promotion
4. Objectively promoted sales of new GPRS mobile phones
