Hi Victor,

Regarding the HTTP POST, you can find details about the different ways that you can submit an MMS message to NowSMS at the following link: ontent/Submitting_MMS_Messages.htm

There is a PHP example here:

There's also a Java example:

With some more helpful info on that example here:

Note that it is not necessary to create a compiled MMS message before submitting it to the server. Some of the examples do this, but you can instead attach multiple files to the request, and the server will take care of any necessary MMS formatting.

Before you do any of this ... however ... I'd suggest that you work on getting NowSMS configured so that it can properly submit MMS messages via its built-in web form. Because if that is not working properly, the format of your submissions will not matter.

I'm not sure about the specifics of Telcel México, however, I suspect that you will need to configure NowSMS to send messages through the operator MMSC over the GPRS modem. For more background on MMS, and the two different types of configurations for NowSMS to send messages, see

For more details on configuring NowSMS to connect to an operator MMSC over a GPRS modem, see: ontent/Connecting_to_operator_MMSC.htm

The above link talks about connecting to an operator MMSC in generic terms. Of course, you will need the specific settings required for your mobile operator.

The GPRS Access Point Name (APN), and WAP Gateway IP address are a good start. But, at a minimum, you will also need the MMS Server URL.

I did a quick web search to find the details for Telcel, and I found that you may also require a username and password to be configured for access to the APN.

Based upon my findings, this is what I believe you would need to configure to define an "MMSC Routing" to the operator MMSC in NowSMS:

“Account name” and “Account Description” are settings that identify the connection to the Now SMS/MMS Gateway only. These settings are not transmitted externally, so use any value that is meaningful to you.

“Default Sender Address” should be left blank.

“Allow Sender Address Override” should NOT be checked.

The “Route messages to this account for recipient phone number(s)” field is an address mask for defining which recipient phone numbers should be routed to this account. In this case, leave the field blank, and after configuring this account, select it as the "Default Route:" on the "MMSC Routing" configuration dialog.

The “Route Messages Via” option should be set to MM1.

The “Server Address” field should be “”.

The “Login Name” and “Password” beneath the “Server Address” field should be left blank. (This setting is usually not used for connecting to an operator MMSC over GPRS.)

Check the “Use Specific Network Connection (GPRS Modem)” checkbox.

In the “Network Connection” , select the entry for your modem, which is prefixed with the text “Modem:”.

(Note that you must have a Windows modem driver configured for the modem. Although NowSMS can talk to a COM port directly for SMS through a modem, it needs a Windows modem driver configured for the modem when doing MMS over a GPRS modem. Wavecom doesn't publish a modem driver for their modems, but you can manually add the "Standard 33600 bps Modem" driver included with Windows. Don't worry about the 33600 bps reference as the driver actually talks to the modem at 115200 bps. Configure NowSMS to use this named modem driver, instead of the direct COM port reference, in the "SMSC" list, as well as here.)

The “WAP Gateway IP Address” field should contain the IP address of the operator WAP gateway which will act as a proxy for connections to the MMSC, which in this case is “”.

The “GPRS APN” field specifies the GPRS Access Point Name (APN) to be accessed for connecting to the MMSC, which in this case is “”.

The “Login Name” and “Password” parameters specify a username and password to be used for connecting to the GPRS network. Based upon the information that I have found searching the internet, I believe you will need to specify “mmsgprs” and “mmsgprs2003”, respectively.

The “Test Connection” dialog verifies that the Now SMS/MMS Gateway can initiate the GPRS connection, and connect to the configured WAP Gateway IP address, but does not actually test validity of the “Server Address”, which can only be tested by sending a message, after you have completed this configuration.

Remember, after configuring this account, select it as the "Default Route:" on the "MMSC Routing" configuration dialog, so that NowSMS will use it as its default route for sending out MMS messages.

Then, try sending an MMS message from the web interface.

If it doesn't work, try enabling the debug logs on the "Serial #" page of the configuration dialog, and then post the SMSDEBUG.LOG and MMSWAPDEBUG.LOG to me as an attachment, so that I can investigate.

Hi Bryce!

thank u for give the response.
I have the right configuration in the nowsms, i tested it sending sms and mms via the web inteface and the messages are send correctly. I receive them with no problem!

The problem i had, is trying to POST the Multimedia message, i write a little script (PHP) for doing that, i have made a connection via a modem with my wavecom modem connected to the COM1 port, so i connect to the APN (, then I open a port through a socket to the Wap Gateway(, here i try to post the message but it still doesn't work.

The response that i receive are 2:

-HTTP/1.1 403 Forbidden Content-length: 246 Content-Type: text/vnd.wap.wml Connection: Close

Request not authorized to access WAP Gateway.

Where is the problem, i undestood that the Gateway undestood my post but refused it! where is the problem?

My objective is to send MMS message with put the NowSMS, it is for my tesis project, u think is possible to do that?

thank u bryce!

Hi Victor,

It's hard to say. If NowSMS can do it fine, then my work is done, isn't it?

We do our posting via WAP/WSP by default ... not HTTP. (You can configure us to use HTTP instead by changing the “WAP Gateway IP Address” setting to be start use a format of “http://ip.address:port”.) We have better control using WAP/WSP and managing multiple modem connections to the same MMSC, whereas some control is lost using HTTP.

So your script is not doing exactly what NowSMS is doing. It may be a problem with the format of the request that you are sending.

Sorry ... this is the support forum for the Now SMS/MMS Gateway software product.

I can't tell you how to configure your mobile phone. My suggestion would be to try downloading a manual from the handset manufacturer's web site, and see if you can determine where these settings are configured on your mobile phone.
