Troubleshooting for Nokia products

If you change the network service provider, the internet Access Point Name (APN) settings may be incorrect.

1. Download and install the Network Setup app from Store (Marketplace).
2. Restart your phone.
3. If the problem persists, start the Network Setup app and configure the internet setting by adding a new APN (+). Contact your network operator for internet APN settings.

You can use Microsoft SkyDrive as additional storage. For more info, go to https://skydrive.live.com.

In Windows Phone 8, use the Storage Check app to clear several types of temporary files. You can download the Storage Check app from Store.

1. If you have Nokia Lumia 505, 510, 610, 710, 800 or 900, download and install the Network Setup application which can be found in the Nokia Collection on Store (Marketplace). To set up Internet and MMS settings, start the app and select your network operator.
2. Confirm with your network operator that you have an active mobile data subscription (access to internet).
3. If the data connection is lost, try reconnecting by switching Flight mode on and back off: Tap Settings > Flight mode. This resets the active data connection.
4. If you have a known Wi-Fi network running in the background, this can trigger the Wi-Fi network connection to be established. The Multimedia Service (MMS) is a cellular network function and is not used when connected to Wi-Fi. In this case, tap Settings > WiFi and switch WiFi networking off. 

The blinking closed envelope icon indicates the SIM card message memory is full.

Select Menu > Messaging > Options > (View folders > Options) > SIM messages and delete one or more SMS messages.

Note 1: Class 2 messages (for example, service messages from operators) are stored in the SIM card message memory. Once the SIM card message memory is full, Class 2 messages can't be received. 

Note 2: You have used a Nokia S40 product before. In S40 products the SIM card message memory is filled before the device message memory. If you insert a SIM card with full message memory to another device, a blinking message icon appears on the display of your Nokia device.

Note 3: Other reason could be that there is not enough free memory available on the device to store the new message. To release a space go to Messaging > Inbox and remove unnecessary messages

If you cannot connect the headset to the compatible phone, proceed as follows:

• Make sure that the Bluetooth feature is activated on the compatible phone.
• Make sure that the headset is switched on and paired with the compatible phone.
• Make sure that you have disconnected the previous Bluetooth connection from the phone.
• Check that the headset is within 30 feet (10 meters) of the phone and that there are no obstructions, such as walls, or other electronic devices between the headset and the phone.
• The pairing information list of the headset may be full. The headset can store the information of up to 8 phones at a time. If the list becomes full, reset the headset to the original settings (for detailed information on how to reset your headset, see the User Guide of the headset).
• If the headset does not automatically reconnect to the default or last user phone, press and hold the Answer/End key.

If your memory card or mass memory is not working properly, check the following:

1. Use only compatible memory cards approved by Nokia for use with your device. Check the user guide or the technical specifications at Nokia support pages for more details
   
2. Check that the memory card is properly inserted in the memory card slot. Push the memory card to the bottom of the slot.
3. If possible, test with another memory card to see if the issue is in the memory card.
4. Check that the device is not connected to PC. Depending on the device and the connection mode, the PC may reserve the mass memory and memory card for exclusive use and the memory drives cannot in this situation be accessed from the mobile device. Unplug your device from PC and try again.
   

If the memory card or mass memory is not working properly, try backing up any data from your device's memory card or mass memory to your PC, then format the memory card or mass memory by using your Nokia device. Depending on your device, the memory card can usually be formatted in one of the following applications (select the application, open the desired memory device and in the available options select the command to format the memory card or mass memory):

• File mgr.
• Memory tool
• Memory card tool

Refer to your device's user guide for more information on how to format the memory card or mass memory.

If you get an error message during the formatting process or an error message after formatting stating that your device cannot read the memory card volume or mass memory, take the memory card or Nokia device (in case you have internal mass memory in your device) to your nearest Nokia care point.

Warning: Formatting your memory card or mass memory will permanently erase all data stored on the memory card or mass memory. Please back up all data stored on your memory card or mass memory before formatting.

Important: The memory card or mass memory inside your Nokia device should ONLY be formatted using your Nokia device. Do not attempt to format your memory card on another device such as a PC, otherwise your memory card may not work properly.
 

The calling phone number may not match with a contact name and the name is not shown in the following situations when an incoming call or SMS arrives:

• The contact is defined twice in the Contacts application (e.g. if both Phone memory and SIM memory contacts have been selected to be displayed in Contacts settings and the same contact is found in both of them).
• The same phone number is defined for two or more contacts.
• The phone number in Contacts application is in different format than the number received in the incoming call. The phone number may have been stored in local format while the incoming call number is in international format (including country prefix), or vice versa. The number may not be properly matched with a contact name in this situation, depending on the device variant and the length of the calling number. In order to verify the correct format of the contact phone number (local or international), check the number which is shown when the call is received and edit the contact details accordingly.

If the problem persists, make sure your Nokia device is running the latest software. For downloads and assistance, go to your local Nokia website.
