How can I receive a short message of more than 70 words without splitting it?

3 1# I am not a moderator, but I have been engaged in the mobile communication industry for many years. Let me answer this question: 1. The limit of short message byte length is defined by communication protocol, just like the length of IP packet, and it is not determined by users or network providers; 2. No matter what kind of mobile phone (except the cottage, the reason will be mentioned later), it must communicate according to the communication protocol, so long short messages must be split (with specific tags in the protocol) before they can be sent. When the mobile phone receives multiple short messages with specific tags, they will be merged automatically, so the user only sees one; 3. Short messages are charged according to the number of protocol packets, so long messages are also charged according to multiple messages; 4. Because some shanzhai mobile phones don't have the function of merging long short messages (that is, multiple short messages are merged into one at the terminal according to the specific label in the short message protocol), the part exceeding the standard short message length will be discarded, so most short message distribution systems (including the special service platform of operators) will split the long short messages that need to be sent (without specific labels) so that shanzhai mobile phones can receive the complete content, which is also the reason why long short messages are split into multiple short messages. Please point out the shortcomings!
