Good day. Thank you for your question.
May I know what information would you like to receive while in the mining area? If there is no GSM signal in that area then I will suggest a combination of FMB640 + TSM232 (satellite terminal) but only the GPS data and other additional data but not all I/O elements are sent through TSM232.
You can read more about FMB640 and TSM232 here for more information:
However, if the area has a GSM signal then most of our FMB devices will be suitable - https://teltonika-gps.com/products/
Kindly go through this or provide more information on what information that you would like to monitor so I can suggest a more suitable device.
