When Apple phones appear, your operator may charge for the SMS used to activate iMessage. What's going on? How can it not pop up?

In the settings, you can choose to turn off or activate after finding the information point. If it is activated, you will send a short message to the operator.

IMessage is a cross-device network short message service provided by Apple for iOS 5. It allows devices such as iPad and iPod Touch that are not bound with mobile phone numbers to communicate with iPhone instantly, and can send text, pictures and videos, which is basically the functional experience of SMS. As long as the iOS device is upgraded to iOS 5 and can access the Internet, you can send and receive SMS for free and unlimited through iMessage. The security of IMessage is very high.

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.

With iMessage, you can send and receive messages with any Mac user who uses iPad, iPhone, iPod touch or Mountain Lion, as well as send photos, videos, location information and contact information. If you have more than one Apple device, iMessage can keep an uninterrupted conversation on all devices. In addition, you can send text messages, photos and videos to other mobile phones through the cellular network. You can even ask Siri to text you. Just say "Tell Xiaoli I'm on my way" and Siri will help you write and send messages.
