    I updated my lumia 520 to Windows 10 and after being updated my phone is unable to detect my sim. I inserted my sim in another phone and it was working fine. I also tried inserting another sim in my lumia 520 and it also resulted the same error my sim not detecting. Please respond to this as soon as possible.

    This happened on my, had to do a hard reset without using a restore point. It sucks but I needed my phone to work as a phone.
