I bought 2 sim cards and put them in the slot (I cleaned them both) after i run through my language and country it asks for a wifi or itunes I have selected both before same error message after I click next when i select wifi it says " “sim required” “please insert a sim card” BUT after i slide to unlock it says “no sim card installed” “insert a valid sim with no pin lock to activate this iphone” PLEASE HELP
Did U try the sim cards on another phone ? if they worked U need to check the sim reader or the part that will use ur sim card maybe it has a problem
