SMS (text) credits are required and used to send SMS commands to the tracker to change its settings and to send out SMS alert messages.
We are only able to sell SMS credits for trackers bought by our customers.
Usage rates depend on: how frequently a) settings are changed; and b) alerts occur; and c) the number of recipients per alert.
Following purchase, credits will be added to an account within a short time. Our credits do not decay over time.
Switching between Normal and Eco mode, or arming/disarming motion alerts, do not use SMS credits.
The number of remaining SMS credits or the subscription expiry date & number of days remaining, are shown in each user interface.
