Apple phones always appear, and operators may charge for short messages used to activate FaceT ime.

When sending and receiving iMessage, use mobile phone traffic or WiFi network. If the mobile phone uses iMessage to send and receive messages without opening traffic packets, the operator will charge the mobile phone a traffic fee.

IMessage is an instant messaging software launched by Apple, which can send short messages, videos and so on. It has high security. IMessage is different from SMS/MMS service of operators. Users only need the data support of WiFi or 3G network to complete communication.

IMessage uses the new message reminder system of iOS and Mac os to directly push information to the other party's screen, regardless of whether the other party is in the game or locked. If both parties are using iMessage, you can even see the state of each other's speech.

Unicom users will also receive such a prompt. IMessage means that if two Macs have the same version, the information does not need to be charged by the operator. This hint means that operators have to charge information fees, which may be different in different regions and the fees are different.
