FAQ - Frequently Asked Questions
I have tried everything and I cannot get the GPS Tracker to send me a SMS message, what is wrong?
You likely have one of two problems - First, does the SIM card have a balance or is it part of an active account? Make sure the SIM card works. Second, does the SIM card you inserted have a PIN code or security pass code? You cannot use a SIM cards with a security pass code inside the GPS tracker.
