All shipped FM devices are automatically assigned to your FOTA WEB account
In the FOTA WEB, you can assign a task for update: Configuration or Firmware
The installed device will automatically detect APN settings and connect to the FOTA to download configuration file.
FM trackers out-of-the-box are ready to use. You just need to insert a SIM card and power up device, then tracker will automatically connect to the FOTA server for configuration - you do not need to configure device manually.
