I am building an Arduino-based device that needs to send data over the internet to a remote server. It needs to do this as frequently as possible but also use as little bandwidth as possible. It will probably work over GSM/EDGE (cellular networking).

The data I'd like to send is about 40 bytes in size - really minimal. I'd like to send this packet to the server about once a minute, but also receive a packet of around that size in response once in a while.

The bandwidth on my server is no problem - the bandwidth on the device's internet connection is, i.e. the cellular data.

Do headers on mobile requests and responses count as part of the bandwidth?

Yes, the total packet size is all data that is sent. Assuming a TCP packet you lose 20 bytes right from the start. If you get intimate with Wireshark you can see exactly what's happening.
