I bought Truphone sim card for my Teltonika device and in the description they say "The vast majority of professional Teltonika customers consumes between 3 to 6 megabyte/month (i.e. 180 to 360 MB in 5 years) per correctly configured Teltonika FM device."
What is the correctly configuration parameters of FM device for reduce usage to 3-6 megabyte per month?
Thanks
