Paying any $$ to build GPS tracker

I am trying to build a GPS tracker using the NEO 6M module and Argon.
Please any help

#include <SoftwareSerial.h>

does not work in particle

There is a ParticleSoftSerial library that works on Gen2 devices but not on Gen3+ (including Argon).
However, there are hardware serial ports on all of the Particle devices that you can use and typically are the better solution over software implementations anyhow.
