GPS/GNSS is not dependent on cellular network.

Thanks for sharing the tip.

Is your OBD port very inside? Device needs to be exposed to sky. Otherwise, external GNSS receiver is recommended.

Try leaving APN blank if using Freematics Builder or setting APN to "" in config.h

Not very sure but can you check the raw data that traccar received?

Please use PlatformIO to compile if you want to use BLE.

SIM7070G requires LTE-M network support otherwise it can fallback to GPRS.

GPS data is not from SIM7600 cellular module. Instead they are from the standalone u-blox M8.

Are you able to connect through iOS or Android app?

This is a good application. You need a bit coding and external buzzer is also possible.
