I have a boost nextel phone with accutracking and a motion detector pro installed.
It has worked well for a couple months but lately stops tracking especially at night. The car is traveling but it doesn,t register at times.
Sent it back to my tech man for a check and it was perfect for him.
Got it back ,got a position fix 100% charge and no tracking 2 days.
Yesterday some but not all. Car came home but last position 12 miles away.
Today I took it out and the phone read "Check SIM card, Emergency calls only" Turned it on and off ,got a fix with some difficulty and its still shows Last nites 12 mile away position. All my accts are paid and active.
Help, please if you can.
