Look closely at the sim card and see if there's any make scraps or wear marks. then look in the sim slot and see if all the pins are visible there should be 6 pins in 2 rows of 3if the pins happen to his on a bad spot on the sim card it wont read and it only takes one bad contact to kill the signal. You may need to replace the sim card
