Why does the indicator light flash quickly when the GPS tracker is turned on?

2011-2-16 After the GPS tracker is turned on, one-minute flash is normal; because the tracker is searching GSM signal. But long-time flash is abnormal. Maybe the SIM card is loose, which cause loose contact; or the PIN is lock; or the direction of the SIM card is incorrect, which cause the tracker is out of GSM service area; or the SIM card is broken; or you use non-GSM web card, etc.
