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:
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.
If this does not resolve the issue, bring your phone to the nearest Nokia Care Centers for inspection.
Your phone is equipped with one or more codes to protect it against unauthorized use.
The PIN and PUK codes actually protect the SIM card, 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 PIN and PUK codes.
Please contact your operator or service provider for assistance with your PIN and/or PUK codes. If you have already contacted your service provider and the code provided did not work, you will have to obtain a new SIM card from your operator or service provider.
Your phone is equipped with one or more codes to protect it against unauthorized use. The PIN and PUK codes protect the SIM card, while the security code protects the device itself.
If your phone is prompting you for a security code and you have not activated one, please try the following:
Please note:
Some operators configure phones so that they only work with their SIM cards. In this case, if you enter the wrong code three or more consecutive times, the phone may lock permanently. If this happens, contact your operator or service provider for assistance.
In other cases when you enter the wrong code three or more consecutive times, the phone switches to a "sleep mode" and does not accept any entries for the next 15 minutes. In this case, power the phone off, then back on, let it sit idle or untouched for 15 minutes, then try again.
If your phone appears to have problems with power, the problem may be with the phone, the battery, or the charger. Before bringing your phone into a Nokia Care Centers for inspection, please perform the following checks:
If you are unable to test your phone or it still keeps switching off, please bring it to the nearest Nokia Care Centers for inspection.

If your charger is an authentic Nokia charger compatible with your device and you continue to receive the message, please bring both the device and the charger to the nearest Nokia Care Centers for inspection.
Charging times differ between charging models. USB charging is limited by the maximum current output of the USB device, and may take longer than charging with conventional chargers.
However, if your phone clearly seems to be taking too long to charge, please bring the device and the charger to a Nokia Care Centers for inspection.
Dropped calls or low sound quality during calls can result from low signal strength or momentary gaps in network coverage, either at your end or the other end of the connection.
In most cases, your operator or service provider is the best source of assistance with issues regarding signal strength.
If you continuously experience low signal strength in a certain area, it may be that network coverage is insufficient there. Your operator or service provider can provide you with more information on network coverage.
If you believe that the problem may be with your phone instead of the network:
If there are still problems, please bring your phone to a Nokia Care Centers for inspection.

If your inbox is full, you may need to delete some messages before new messages can be received. If you are having other problems with text messaging (SMS), please bring your phone to a Nokia Care Centers for inspection.
In order for multimedia messaging, email, and Internet access to work, they must be supported both by your device and by your contract with your operator or service provider. In addition, your device must have the correct settings.
If settings, support, and software have been verified and you are still unable to access the Internet or send or receive multimedia messages, please bring your phone to a Nokia Care Centers for inspection.
Please note: Email may require more complex configuration. Some instructions are provided in your user guide, but often you will need the support of your email service provider or your company’s technical team to install and configure email properly.
Like most electronic devices, your phone may heat up during charging or prolonged use. There is normally no cause for concern.
However, if you feel that your phone is heating up to an abnormal temperature or too frequently:
If it still seems to be heating up excessively, please bring it to a Nokia Care Centers for inspection.
While the theoretical minimum to get a satellite fix is approximately 40 seconds, in practice the required time is usually a minute or more. This can be shorter if the GPS receiver is restarted in a location where it has been used before, while establishing a GPS connection from a vehicle may take longer.
For best performance, the GPS receiver needs unobstructed satellite visibility. Environmental factors, such as tall buildings or cloudy/rainy weather, can affect signal quality.
If you are having problems establishing GPS reception:
If you still have problems with GPS reception, please bring your Nokia phone and/or Nokia GPS receiver to a Nokia Care Centers for inspection. You can find Care point addresses from the drop-down menu to the right.
Note: GPS takes its power from the battery. Using an internal GPS receiver or a Bluetooth connection to an external GPS receiver may drain the battery faster.
