Some guys like to remind me who they are in the text. Like for example, "Hi, I am the guy in the bus with you earlier."
or when a guy gets a new phone and they texted me a couple messages and then say "Hi, this is name. Not sure if this the same number."

It's because they want you to remember them.
Some people just simply forget the people they've met a day or two days before.
Also, it's to remind the small moment you've shared.1
