Hello. I have an issue with my SIM card where my phone for some reason does not want to recognise my SIM card and number making my signal symbol always on🚫. I've also tried everything, put it back in, check for any issues, nothing. When there is signal it barely works. What should I do? Thanks.
Try a different sim card in your phone and see. If that doesn't work then try factory resetting your phone and if that doesn't help then contact Samsung support team.
