here is a general procedure to understand how MMS works. In this
procedure, a photo is being sent to another compatible phone.
Step one: Take a photo from your built-in camera phone or download via
Step two: Personalize the text, graphics, audio or video clips.
Step three: Add recipients' number and send.
The recipient on the other side will receive a message alert. Once he
opens the message, a picture message will appear on the screen. If there
is any text, it will appear below the image. In case, you send MMS to a
non-compatible cell phone - the recipient will a SMS with a default
line, "You have been sent a picture message!"
There are many challenges that exist with MMS:
Adaptation of multimedia content: There may be a difference in the
compatibility of multimedia content for different brands of cell phones.
If the network operator is supporting your content adaptation - you can
enjoy compatibility with more networks and vice versa.
Cell phone configuration: Multimedia Messaging Service requires some
parameters to be correctly placed in you handset. Sometimes, due to poor
configuration, you may not receive messages.
Bulk messaging: Sometimes, if you send MMS to a large number of
subscribers, there might be some difficulty in sending messages. Now
transactional overloads are being optimized.
Moreover, there are several similar terms such as Enhanced Messaging
Service (EMS) - very similar to SMS (Short Messaging Service), allowing
you to send or receive messages with some special text formatting
options such as bold, color, sound effect, icons, etc.
