The SIM card is the small card inside your phone that establishes the network connection. In almost all cases, your
operator or service provider is the best source of assistance with SIM card problems.
Your phone may display a SIM card error message if:
- The SIM card is out of alignment.
If the phone has recently been dropped, bumped, or opened, the SIM card
may need adjusting. Follow the SIM card installation instructions in
your user guide.
- The PUK (Personal Unblocking Key) code is entered incorrectly
multiple times. This can inactivate the SIM card. If inactivation
appears to be permanent, contact your operator or service provider for
a new SIM card.
- You have recently changed service providers.
In this case, either your SIM card or your phone may be configured for
your previous operator and may require reconfiguring. Please contact
your current operator or service provider for assistance.
If none of the situations above apply and you continue to receive this error message, your
SIM card may be damaged. Please contact your
operator or service provider to have the SIM card tested and/or replaced.
