sometimes the pins in the phone (little gold prongs) get a little dirty. try opening phone to see the sim contacts..check for dirt/flattened/broken pins etc. If they are too flat you can try lifting up (gently they are fragile) with a small toothpick/tool. Clean with electrical cleaner (something high in alcohol content so won't leave residue) let us know if this helps

Try opening the phone to see the sim contacts and check for dirt/flattened/broken pins etc. If they are too flat you can try lifting them up (gently as they are fragile) with a small toothpick/tool. Then, you can try cleaning them with an electronics cleaner (something high in alcohol content so won't leave residue). Let us know if this helps
