This evening my phone just started giving me every single one of those three error messages. invalid SIM, SIM card locked- please power cycle, and unable to detect SIM- restarting phone to check for SIM, etc. there has been no trauma to the phone, nor any updates have been installed. I have an iphone 6S. I have never experienced any issues like this before with Virgin Mobile. I have been a customer with Virgin Mobile for over 10 years. l have removed the SIM card repeatedly, wiped it off, power cycled. I would like a new sim card mailed to me.
