Back in 2010 when I was into Arduino I made a GPS/GSM Car Tracker with my Arduino Mega (ATMega 1280, an 8-Bit 16MHz MCU).
I did that by speaking AT serial to a Telit GM862-GPS module. I can’t find the actual CPU spec now but it contained a much more powerful CPU, I recall it being ARM but can’t find evidence of that now :) it also had a python interpreter.
Same energy.
