Activate iMessage on Apple's mobile phone.

1iMessage is directly integrated into the "information" function of Apple devices (that is, the program that we send messages on iphone). To check whether iMessage is supported, please set-> General->; About this machine, check whether your iOS version is above 5.0. On all iOS devices, including the iphone4s, the iMessage function is not turned on by default and must be set before-> Activate imessage in the information menu, as shown below.

2 In the information setting item of 2iPad, the default iMessage is grayed out. When you pull the switch, a verification message will be sent to Apple's official server. After about 1-2 seconds, it will display blue, indicating that iMessage has been activated.

When you send short messages to other users with the information function, if the other party is also an operating system above iOS5 and the iMessage function is turned on, the message sending button will turn into a blue bubble within 1-2 seconds (traditional short messages are green bubbles). And the messages you sent him were also distinguished by blue bubble charts. (Please see the places circled in red in the picture below.)

At this time, if you send a short message to the other party, you will use the blue bubble base map to distinguish it from the traditional short message. On the other hand, if the information you send is green, it is a traditional short message, and China Mobile is 1 cent, so you should send it slowly.

4 SMS messages sent by iMessage will be displayed in blue bubble basemap, while traditional SMS messages are fluorescent green. Because iMessage is based on Internet data transmission technology, it can send data files in almost any format, such as pictures, videos, files, mp3 and so on. You can think of it as an advanced version of MMS, faster and better. The only problem is that the other party must also be an iOS device.
