How do black and white short messages become color short messages?

MMS is a completely different information service from ordinary SMS. It belongs to the upgrade service of SMS. Can send color pictures, text, audio streams, ringtones, based on SMTP protocol, a bit like ordinary mail. When a mobile phone receives MMS, it needs to set the server URL of MMS first, which is a bit like setting up a mail server.

When sending, the address of the receiving user will be "+8613900112233 @ mms.gmcc.com" and so on. The front part is the complete mobile phone number, followed by the domain name of the multimedia short message center server. Does it look like an email address?

Therefore, for mobile phone users, sending and receiving MMS messages is just like sending and receiving emails. However, it should be noted that although MMS can be sent to an ordinary email address, it can only be displayed when the mail receiving software, such as Outlook, Foxmail and other unique SMIL that supports MMS.

The MMS multimedia message will be first stored in the server of the multimedia message center, and the user will receive the message of the MMS multimedia message. After the user needs to confirm, the machine will receive MMS messages from the MMS server through GPRS, just like logging in to receive emails, but no password is needed. It doesn't matter if the user doesn't intend to download this information. In addition, MMS uses reception confirmation and reading confirmation functions to let the sender know whether the receiver has seen his MMS.

MMS multimedia messages can be sent by mobile phone just like ordinary messages, allowing users to add pictures and sounds. In addition, it can also be sent through the website, because SMTP protocol is used, so it will be easier to design the website.

4. MMS production process

MMS integrates images, pictures, ringtones and words into a short message and sends it out, which makes mobile communication more interesting and vivid. So how is it achieved? Take SonyEricsson T68i as an example to introduce it.

The process of making MMS is as follows:

5. MMS production skills

First of all, you need to have image processing tools and basic processing knowledge (such as Photoshop, ImageEditor and other tools that can edit, process and make images). Generally, the generated image is within 10 1 X 80 pixels, so the source image does not need too high resolution.

If you need to record your own voice, you need a microphone and recording software (the simplest thing is to find a tape recorder directly in WINDOWS). Moreover, the recording file format needs to be a WAV file of 16Bit, otherwise it will not be converted into an AMR file supporting MMS format by the sound conversion tool provided by us.

If you want to make MMS more personalized, I suggest you install another MMS_Composer, so that you can make professional MMS. Please go to the next section: 5. MMS solution of company and 6. MMS mobile phone)
