The difference between blue and green when sending text messages on Apple mobile phone.

Different scope of use, different charging standards, different information synchronization and so on.

1, blue SMS multimedia support; Green SMS is a traditional SMS and does not support multimedia.

2. Blue SMS can be sent for free, and green SMS will be sent for a fee;

3. Blue SMS realizes message synchronization among multiple Apple devices; Green SMS is out of sync. The switching between blue SMS and green SMS is automatic, depending on the receiver's equipment and settings. If it is sent to users of other Apple devices, iMessage (blue SMS) will be preferred for transmission; If it is sent to users of non-Apple devices, it will automatically switch to traditional SMS (green SMS). Blue SMS means that you are using iMessage to send messages to users of other Apple devices through the Internet. Its advantages are more functions and free sending. Green SMS means that you are sending messages to users of non-Apple devices through traditional SMS service, so you need to consider the cost and popularity of SMS.
