Hi everyone, If I have understood correctly, when a mobile receive a MMS, it actually receive a MMS notification (via wap push) containing a link to a page on a HTTP server. Then the mobile go to this location in order to retrieve the content of the MMS. Am I right ? If I am right, then I have several questions : 1- Using nowSMS, what informations should I feed the wap push form with in order to tell a mobile to fetch a MMS on http://abcdef.com/mms4587/ 2- And how the mms data should be made available on the http server in order to allow the phone to retrieve them ? (which file format, which directory structure, etc) mms file compiled with MMSCOMP ? Actually, I'm working on a project for which I need to send video to users that are larger in size than what is usually allowed by operator MMSC (size limit is about 300kB). So I would like to be able to feed users phone with my very own unprocessed unshrinked data. I'm absolutely new to this field, and although the related article I found on nowSMS website gave me valuable informations, they did not gave me answers. Thanks in advance for your help ! | |||

Hi Frederic, One thing to keep in mind that the reason for some of the operator limits is because many terminals have MMS size limits. That said I'd encourage you to read this article if you have not already: http://www.nowsms.com/faq/how-mms-works That article goes into some good detail to explain how MMS works. At a purely technical level, yes you can send a link directly to your own content. However, at a more practical level, your recipients may not be able to access it. It is an issue of economics. Many mobile operators charge a flat price per MMS (some with different size categories), and do not charge for the associated data transfer. As such, the MMS settings on the user phone will be configured to use an MMS only access point that can only talk to the operator MMSC. In some cases you could change the phone settings, but then the phone loses connectivity to the operator MMSC. All that said, your assumptions are technically correct. The MMS message content must be packaged up in MMS encapsulation format, which is the format created by MMSCOMP. The only requirement of your web server is that it have the MMS MIME type configured. You send an MMS notification to the recipient which includes a URL pointer to your MMS Content. The following articles go into more detail on this type of setup: http://www.nowsms.com/doc/submitting-sms-messages/sending-mms-notifications-and- content http://www.nowsms.com/doc/advanced-configuration-settings/creating-mms-message-f iles -- Des NowSMS Support | |||

Thanks for those informations. MMS size limit imposed by the terminals is not good news for me. Actually, I think there is no solution which can fulfill my needs. Pushing a URL via Wap Push is not ok, as the message is not usually kept after it has been clicked. And I need the users to be able to restart the video if they want to. MMS with a link is not ok, because I need the URL to be hidden (for aesthetic reasons), and even if SMIL allows to make an image clickable (with a simple hyperlink tag), this is not usualy well supported by the terminals (or at least by iPhone). Do you know any other solution which would let me send media that users could play seamlessly (I mean, without seeing all the weird technical details) | |||

I hate to say it, because I wish there was a better way ... but a text message including a URL link shortened by one of those link shortening services is the approach that I'd probably end up using. A few years back, one of my colleagues wrote an interesting article on the topic of streaming video in MMS. It is at the following link: http://support.nowsms.com/discus/messages/485/4325.html His analysis (7 years ago) was that SDP was the recommended solution for delivering streaming video via MMS ... but nobody had implemented it. Unfortunately, I don't think anything has changed. -- Des NowSMS Support | |||

Hello, a question regarding SMS with "big" images: indeed, I send MMS of different sizes (100 ko, 300 ko, 550 ko) from nowSMS to my phone A: - when I use the internal MMSC router, my phone A receives properly all the MMS. - when I use the operator MMSC, the same phone A receives MMS only when their size is lower than (approximatively) 320 ko, it never receives bigger MMS. I see no error in nowSMS interface when sending the MMS. I thought it was a limitation due to the operator MMSC. But then I use a phone B instead of nowSMS to send the same MMS to the same phone A, through the same operator network and MMSC, and my phone A receives all the MMS. So the operator network and MMSC don't limit the size of the MMS ... Is there a parameter to set or some limitation on the MMS size when using an external router ? Here are my settings: MMS outbound routing MM1 Use specific network connection GRPS modem Thanks in advance for your help, Regards, Cecile. | |||

Hi Cecile, You may be able to get around this limitation by changing the MMS settings in NowSMS to use a WAP2 gateway address (the current settings we supply are WAP1). To configure a WAP2 gateway address, in the WAP gateway address field, use the format http://ipaddress:port (the http:// prefix tells NowSMS to use WAP2). If you need help locating this address, please advise which mobile operator you are using. Note that this may not resolve the issue, as many mobile operator MMSCs have limits in the region you describe. Different devices also have size limits that can be frustrating for sending video via MMS. Unfortunately, to the best of my knowledge, the streaming technique described earlier in this thread has not seen any real world implementation. -- Des NowSMS Support | |||

Thanks for your answer ! The operator is Bouygues Telecom - France; do you know their WAP2 gateway and port ? Should I set this parameter in "MMS outbound routing/Specific network connection" or somewhere else in the interface ? Best regards, Cécile. | |||

Hi Cécile, I believe that http://62.201.129.225:8080 is the correct setting. You are correct, it is the WAP gateway address under the settings you describe. -- Des NowSMS Support | |||
