My sim is inserted in to my Nexus 5X but the phone wont recognise it and keeps saying no sim inserted so I have no coverage. It used to recognise it until it randomly started asking me to insert my pin every time I was on my phone saying the sim was locked, this wouls happen even if I was in the middle of using the phone, then all of a sudden it just stopped recognising the sim at all. I've tried taking the sim out and putting it back in but it did'nt work.
