How much did it cost to set up a TCP connection?

I am creating an application in which my phone often sends data to my server. Since I will use my mobile data, I wonder how much data it cost to set up (and demolish?) The TCP connection to my server.

Device 1 sends its TCP sequence number and maximum segment size to device 2.
