1 It is showing an invalid sim card
worked fine this morning, got to work and it read invalid sim card at the top of the phone and does not work at all. It is a straight talk phone LG Stylo 3 from walmart. Help me fix it please!!! I've tried taking out the sim card and putting it back in, turning the phone off and back on and nothing
Did you first activate the SIM card with your wireless provider?
