How can android display a long short message as a short message?

Some mobile phones can't accept complete long short messages due to version restrictions, which involves many problems:

1. When will the mail be unpacked? This problem is actually related to mobile phone terminals. Some terminals are automatically split into several normal short messages, and some are long short messages; I will see the agreement later;

2. The order of sending after unpacking.

If the terminal sends several normal short messages, the receiving terminal will display them in the order of receipt. It shows several short messages.

If the terminal unpacks and sends an extra-long message, the SMS center/SMS gateway will forward the message according to the protocol requirements. After receiving any of them, the receiver will not display them immediately. When the number of messages it sees is less than the number of message packets, it will unpack instead of assembling. When the number is equal, a normal short message will be assembled. Let's look at the CMPP protocol:

//When the short message exceeds 70 Chinese characters, the first part of the short message.

E000000//4/Total length of 4 bytes of data

05 00 00 00//4 byte command number

3f38b 0 1//4 byte serial number
