The easiest way to send
an MMS message through the gateway is
to connect to the “web menu interface”.

The web menu interface
provides two methods for sending an MMS
message. The “Send
MMS Message” option
allows you to define a subject, message
text, and optionally include multiple
content files (uploaded via the browser).
Content files may include text files,
audio files, image files, SMIL files,
and/or other supported MMS content types.
The gateway automatically compiles the
MMS message file and uses the gateway’s
built-in MMSC to send the message.

To send your first MMS
message, enter the “Phone

recipient, supply some text for the “Subject”
of the message, and enter some text for
of the message. For your first test, you
may want to leave the “Content

your browser return an error message?
Your browser might return an error
message when you submit the MMS message.
Here’s what happens behind the scenes
when you click “Submit”:
The SMS/MMS gateway creates a compiled
MMS message file, and submits it to the
local MMSC. The MMSC provides the SMS/MMS
gateway with a URL for retrieving the
message, based upon the MMSC configuration
information defined in Step 4. In particular,
the MMSC tells the SMS/MMS gateway that
to retrieve the message that was just
submitted, it should connect to “Local
Host Name or IP Address”
on the “HTTP
Port Number”. If
the MMSC is configured incorrectly, the
SMS/MMS gateway will not be able to retrieve
the URL from the MMSC and an error will
occur. Of course, it is preferable that
the error occur here rather than occurring
when a mobile phone attempts to retrieve
the MMS content, so you’ll want
to correct any configuration errors from
Step 4 before continuing.
Do you receive an MMS notification message,
but are unable to access the message content?
- Re-configure your MMSC to use HTTP
port 80. Some operator WAP gateways
have firewalls that prevent access to
any content that is on a port other
than port 80. If you are sending an
MMS notification message where the content
server resides on a port other than
80, change the content server to use
HTTP port 80. Repeat your attempt to
send an MMS message. Note that changing
these settings will only affect messages
that are sent after the change is made,
they will not change attributes of messages
that were already sent.
- Check the WAP profile that is associated
with the MMS setup in your phone, and
verify that this is the same WAP profile
that you use for regular WAP browsing
activities. It has been noticed that
some operators are setting up restrictive
MMS profiles, where the MMS profile
connects to a separate GPRS APN, and
a separate WAP gateway, which only allow
access to the operator MMSC. After changing
the MMS setup to use the WAP profile
that you use for regular WAP browsing
activities, repeat your test. You should
not need to resend any messages, but
can retry accessing messages for which
notification was already received.
- It is possible that your operator
has constructed a “walled garden”
in attempts to lock users to their content
services. To leave the walled garden,
check with your operator to determine
what GPRS APN (access point name) should
be used for PDA/PC type connections,
and if a username or password is required,
what those values should be. Create
a WAP profile on your phone that connects
to that GPRS APN. Specify an IP address
for the WAP gateway of 184.108.40.206
(this is a gateway at the Now Wireless
offices, if you have your own WAP gateway,
substitute that gateway IP address).
Try using that WAP profile to browse
to a site, such as http://mms.now.co.uk/index.wml.
Switch back to your normal WAP settings
for browsing, but configure the MMS
services on your phone to use the WAP
profile that you just created.
- Are you using your own WAP gateway
instead of the operator WAP gateway,
or does your operator not yet support
MMS? MMS requires that WAP gateways
support “SAR” (segmentation
and re-assembly). Some early WAP gateways
did not provide this support. If you
are unsure about your WAP gateway, you
may want to try using the public WAP
gateway referenced in the previous item.
