The system is updated but simcard is invalid even I buy new one
@paciotti , Nirvana , Visit/contact a retail location for your service provider and purchase a new Sim card and have this card activated by your provider/ or see if they can activate one of your simcards to make it valid. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
