Hello, My SIM card isn't working on my Sony Xperia Z2 and I don't know what to do. My old iphone 4 recognizes the SIM and it's working without problems but the only thing it does on my Sony is restarting the phone
Could be your Sim card needs replacing regardless of whether or not another phone detects it or it could be the Sim card reader is faulty so what I would do it try a new Sim card and if the same happens then have your device checked
