Showing invalid sim


The most common thing for any mobile/cell phone.
Easy fix simply take an eraser & rub over the contact of the sim card then making sure not to touch the sim cards chip re-insert in to the phone & it should be problem solved. If the problem still exists insert in to another phone if possible to test the integrity of the sim card if the sim card works in another phone it could be the phone you are attempting to use it maybe faulty or the sim card is incompatible or the phone is not unlocked entirely, if it doesn't work in another phone the sim card has failed & a new sim card is required.
