What is the difference between MMS and WAP? What is the WAP service of Unicom?

WAP is a way for mobile phones and other portable devices to surf the Internet.

MMS refers to information containing multimedia.

CRBT (Color Ring Back Tone) is a service that replaces the "beep" waiting tone with music, human voice or other sounds when no one answers the phone.

MMS can only be realized through WAP. Only when the mobile phone is connected to WAP can MMS be sent and received.

Just like on a computer, e-mail depends on the Internet.

CRBT is another matter, which has nothing to do with MMS and WAP. You can use it as long as you apply to the relevant telecom operators for opening.

Unicom users can surf the Internet, download pictures, ringtones and images, get information, communicate with more people faster and better, and have many useful functions. For details, please see Unicom New Time and Space: uninet.com/unicom/xuanjian.

I hope this is easier to understand.
