The difference between blue and green text messages.

The color difference in this case needs to be divided into ios system and Android system.

1, ios system: On the iPhone, SMS is divided into two forms. Blue bubbles are short messages sent through iMessage, Apple's own instant messaging service. Can be sent through the Internet, as long as there is a network connection (WiFi or cellular data), you can send and receive for free. The short message of Green Bubble is sent through the SMS of the operator, which is also the ordinary short message. Sending and receiving will incur SMS charges and can only be used where there is a cell phone signal.

2. Android system: Android system and other platforms have no default mechanism to distinguish between blue and green SMS. Short messages are all displayed in green or gray bubbles, and the meaning of color cannot represent different short message service types like ios system.
