Hello I need a obd2 WiFi hotspot gps tracker that uses a gsm chip. I need samples to test in my country to see which can work. I can be contacted at 5016713279 **** Kindly note that I prefer devices that use an app that can be edited since my company does road side assistance and would want to incorporate the gps locater with the roadside assistance service.
