Invalid Card

Hi can someone help me, my phone keep saying invalid card and I don't have any signal. I already try restarting my phone, check if the sim is in the position, I already try to remove and return back the sim and also I already try to clean the sim using eraser but then the word "invalid card" is still there. What can I do please give me some solution for it.
