Naming of mms files received

[Android Central Question]

Can anyone tell me what the number before and after the MMS mean?

Not sure about the first number (might be just thread ID), but the second number looks like the phone number it came from (or received in? you can probably check that better), with country and area code included. Might be wrong though and, again, might be just a system ID number.

Well the first set of numbers are in sequential order. But who’s order the sender or receivers order. The sending is an Samsusung galaxy 5 and receiving is an iPhone X.

I was thinking the same thing. But for the first set of numbers, I was guess pictures taken and saved. THe 21025 thru 21029 were in order received.
