Question about long text messages

[FKV1388]

Hello. I've noticed sometimes when I recieve long texts messages.. that then come out of order but are sometimes numbered for example at the beginning of the message it says (1 of 3) Meaning there are 3 messages this is the first part... Is it only some phones that do this or are the people sending the messages doing this themselves? How can I get my phone to do this if it is the phone?

Any insight would be helpful. Thank You.
