I have the same problem as JIangnan. The phone receive the notifications an part of the message but can play it. Here is what I did:

1) As I'm behind a firewall I uploaded the .mms file on a public Apache Server with a .htaccess file containing the line:
AddType application/vnd.wap.mms-message .MMS .mms

2) I upload the mmstest.MMS file on the server.

3) I used the "Send MMS Notification" page to send a notification to 3 phones: a Nokia 3650, a 3660, and a SonyEricsson T610.

* The 3650 and 3660 phones are displaying saying that they are retrieving the message, and then nothing more.
* The T610 manage to display the subject of the MMS ("test mms from jiangnan"), but fails to get the rest (says that there is a connection error).

4) I tried the same thing by including only the text data in the MMS (mmscomp mmstest.hdr Text0000.txt), with the same result.

Any idea?

Please see http://www.nowsms.com/howmmsworks.htm for a discussion of how MMS works, and an explanation of this issue.

The SonyEricsson phones are better for troubleshooting here, because they will display the MMS notification, and then tell you that there is an error fetching the URL associated with the notification.

This happens because many operators block MMS message delivery from external MMSCs. Please see http://www.nowsms.com/howmmsworks.htm, and then if you have a question after reading that, I would be happy to clarify any issues.

Hi, Bryce:

This works on my nokia handsets(N7600), but not on sony ericsson's phone. I received the notification messages, but during retrieval, got the connection error(same senario as above). Can I conclude that my operator does not block MMS delivery from external MMSCs? and what would be the possible causes? Thanks.

Hi Will,

It is likely that the Nokia 7600 is using different connection settings than your SonyEricsson.

The Nokia 7600 only supports using an HTTP/WAP2 proxy, whereas most SonyEricsson phones only support a WSP/WAP proxy (some newer SE phones can support either WSP/WAP or HTTP/WAP2, but they seem to be much faster using WSP/WAP).

So it is likely that you are using different connection settings between the two devices.

Can either phone send MMS messages to itself? Do this to verify that they actually have working MMS settings.

If they can send to themselves, but the SE phone still reports a connection error, then it is likely that the MMS connection settings configured in that phone point to a GPRS APN and WAP gateway that block access to external MMSCs.

Alternatives in this scenario are posting MMS messages through the operator MMSC (such as over a GPRS modem), or using Multimedia WAP Push.

Hi Swetha,

If you use NowSMS, you wouldn't need to develop an MMS client.

Basically, NowSMS can send out MMS messages through a variety of different connection types.

If your operator offers MMS service provider connections, then they might offer MM7 (standard or Ericsson proprietary) or EAIF connectivity. Or, if the network is open to external MMSCs, NowSMS can act as an MMSC performing direct MMS delivery. Or it can send MMS messages over a GPRS modem (a bit more complicated than sending SMS messages over a GSM modem because there is more than just AT commands involved).

Submitting MMS messages into NowSMS for outbound delivery can use any of the protocols described in the following link:
