(2017) So, we could fit phones inside USB connectors, 4 years ago. Nice >:(

  Just slightly bigger, but one could actually build a similar thing at home literally for change coins: https://www.ebay.com/itm/284022359237 https://www.ebay.com/itm/284022359237 (or search for "SIM 800 module") This one is a module that does GSM voice+SMS communication; just add a cheap GPS module if necessary, a small 8 pin uC that speaks serial, some code, a battery and voila. The problem with these devices is that they need a SIM card which I believe needs some form of registration pretty much everywhere, so unless there is some governmental screen to protect you, if you use any SIM based device to spy on others you'll be leaving behind sensitive traces useable to identify you.

    Aww, if only Australia's 2G network were still up and running (it got turned down back when dinosaurs still roamed the earth :/), and 3G's getting nuked in 3 years as well. These tiny things are so cheap!! Wow... but thinking about it, I'm not seeing SIMCom's logo in the corner, so it looks like some no-name factory somewhere has basically cloned the entire chip. Which is pretty incredible considering everything it does.
