XZ3 SIM card not detected issue

[Keo2019]

For the past couple of weeks my phone randomly shows no SIM card detected then I have to reboot the phone to resolve the issue. Has anyone else experienced this issue? 

I have tried removing and cleaning the SIM even though there are no signs of dust, my phone has a cover on anyways and is always well looked after. 

I have also noticed that when I turn the phone off and back on it takes longer than usual to turn back on. The notification light flashes yellow then eventually turns on. 

I was hoping it's a faulty SIM but worried it's the phone. 

I am going to try the SIM in another handset to see what happens.

I have the same problem ... I tried them all. Restoration, factory RESET. But if it is the update they cannot release another one that goes to correct the errors? I'm also a fan of Ps4, but I'm starting to like the Xbox after this bad experience with SONY. 800 EUROS BY PHONE. NEVER A YEAR OF LIFE. M INFORMED ASK FOR DAMAGES. THERE'S NO HARM IN TRYING.

Ho lo stesso problema... Le ho provate tutte. Ripristino, RESET di fabbrica. Ma se è l aggiornamento non possono rilasciarne un altro che va a correggere gli errori? Sono anche appassionato di Ps4, ma comincia a piacermi l Xbox dopo questa esperienza negativa con SONY. 800 EURO DI TELEFONO. NEANCHE UN ANNO DI VITA. M INFORMO PER CHIEDERE I DANNI. TENTAR NON NUOCE.
