i have a question about sending mms via phone.my operator suppors 3G(HSDPA/HSUPA) .If i use 3G service with my phone will that be effect my MMS upload speed? I mean will that be still use for GPRS for uploading MMS to MMSC, or it will be use HSUPA(up to 384kbps) for sending MMS to MMSC?

Assuming that you are in a coverage area where it is supported, HSUPA would be used.

thanks for the info Des.

I have another question.Let's assume i'm using a GRPS/3G usb modem with my pc, and using a desktop application to send MMS messages(*.mms files) to MMSC.What happens if i want to send multiple mms files to operators MMSC?
I mean while sending a MMS to phone number X, at the same i want to upload another(not the same) .mms file to phone number Y.will it be allowed to upload multiple files to MMSC at the same time or the uploading mms should be completed before i start to upload another?
Or is there any advanced hardware(GPRS/3G modem) that supports that kind of feature?(like MMS queue)

Thank you.

Assuming a single modem configuration, NowSMS sends MMS messages to an operator MMSC one at a time.

(I don't know that this is actually required by the MMS protocols, but this is typical behaviour of mobile phone MMS clients. NowSMS is essentially emulating a mobile phone MMS client.)

Thank you Des.
1-)i need another information about a GSM operator in UK.
Telefonica O2 in UK offers their customers 0.24£ per picture message(MMS), also it can be dropped to about 0.204£ per MMS(pay monthly package).It's the same price for domestic(UK) and international numbers.
So,let's assume if i send a MMS message(O2 SIM using with GPRS/3G modem) to domestic(UK) phone number , my MMS will upload to O2's MMSC.
But what about international MMS? Will it be dropped to other country operators MMSC? I man when i send a MMS file to international(for example: Verizon USA) number,first it'll be upload to O2's MMSC, after that O2 MMSC transfers that MMS to Verizon MMSC correct? so users can recieve MMS with no additinal MMSC settings in their phone?

2-)we know a MMS container file(.mms) has some parts(Sender ID-Phone Number,Reciever Phone,Picture/Video content,Sound content,Text content)

Now here's i want to ask.With a GRPS/3G modem(SIM card Attached to it),i want to send MMS file with a desktop application i use(which creates *.mms file) to another phone.So MMS reciever will see my SIM number on sender-ID.
Now here's i want to know.is it possible to identify unique sender-ID(Name) instead of a phone number for each MMS?

Thank you.

1.) Correct. It goes to your operator MMSC, and that operator MMSC takes responsibility for routing it to the destination operator.

Except in this particular instance, I can tell you that O2 does not have true MMS connectivity to the USA. When an O2 subscriber sends an MMS message to a USA recipient, the USA recipient currently receives a text message with a URL link and a code, and they have to open up a web browser to retrieve the message.

(Because of this issue, you may want to install a separate system with a modem in the USA to handle USA recipients. Personally, I think it's ridiculous that these inter-operator MMS connectivity issues have not yet been resolved!)

2.) No. When you send via a modem, the operator MMSC inserts the sender address when it receives the MMS message. You cannot override it.

For message identification purposes, some people use the MMS Subject field. We actually have a configuration setting to embed the actual sender address in the subject field so that if a reply is received with that subject field, we can route the reply back to the original sender. (However, some devices, like the iPhone merge MMS with SMS, and show a threaded conversation. If the user replies to the MMS with an SMS, there is no subject field to correlate the reply with.)

Thank you Des.

Do you know about MMS Composer Applications for Mobile Operating Systems?
Is there any international standart for Multimedia Messaging Format for MMS Composer/Viewer applications on mobile phones?
For example if send a MMS message via iPhone(ios OS) (using application : SwirlyMMS) to PocketPC(Win Mobile OS) (using application : Arc Soft MMS) can it be viewed on PocketPC? (or reverse the same progress PocketPC to iPhone)

The presentation layer in MMS (which is basic profile SMIL) is so limited that there is generally not an interoperability issue.

There's also not much of a need for a composer application.

Basically SMIL is used for a slideshow type of presentation. Display this image and/or text for x seconds, then display the next image for y seconds, etc.

Different devices have quirks, of course ... and some, like the native iPhone MMS client, don't actually use SMIL when displaying picture messages. The iPhone displays each image or video in a separate bubble within the conversation window. When the iPhone sends an MMS, it does generate some simple SMIL to keep other phones happy.

So I guess the bottom line is to keep it simple.

If you submit the individual message components as separate files (instead of building a pre-compiled MMS), NowSMS will automatically generate simple SMIL for you.
