The cost to cover the re-activation of a de-activated SIM. This covers the average cost charged by different SIM suppliers to reactivate a SIM as well as the cost of the internal/external administration.
It is usually, but not always, possible to reactivate a SIM. The SIM reactivation charge only applies if successful. See the following extract from our Terms of Service:

Use it or lose it:
SIMs, and tracker accounts on the Trackserver platform, are both deactivated when/if a tracker/SIM has not communicated, or updated its GPS location, in the 100 days following the tracker's subscription expiry date. Trackers can communicate/update only if their subscriptions are maintained/current.

GPS2Find is required to avoid monthly payments (SIM rental, data and platform) for trackers/SIMs that are no longer in use, or being paid for.

It is the customer's responsibility to renew their tracker's subscription, although GPS2Find will endeavour to make contact, regarding subscription renewal.
