Troubleshooting for Nokia Lumia 710

1. Check your SMS settings by selecting Messaging > Msg. settings > Text messages > Message centre.  
   
2. Verify that you can make a call.

SMS message may get converted to MMS message in the following situations:

1) When sending a long SMS message

In some devices the message type gets converted from SMS text message to MMS multimedia message if the message length exceeds the device-specific setting which is typically 5 - 10 SMS submessages (around 760-1520 characters). If the message is longer, it is converted to MMS to avoid potential issues in handling long text messages in the recipient device. The cost of a SMS message consisting of several concatenated submessages may also be higher than the cost of a single MMS message.

The conversion from SMS text message to MMS multimedia message occurs when the automatic message type is selected in the message options. This is the default mode where the device tries to automatically select the best mode for the message.

The conversion from SMS to MMS can be avoided by selecting Options > Sending options > Message type > Text when in the Text message window writing the message. The message is then always sent as SMS text message and no conversion to MMS occurs.

The maximum number of concatenated SMS submessages can be up to 10 (around 1520 characters). In multimedia mode the message length can be longer.

2) No phone number defined in user contact information

If sending SMS to one or more recipients and one of the potential recipients has only email address and no phone number, the SMS will be converted to MMS. This is independent of the number of the potential recipients.

In order to avoid the conversion to MMS, remove from the recipient list the contacts which don't have a phone number defined.

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. If you see the APN editing option under Network Setup menu, tap on the Edit APN, and then select delete.
2. If you have any other Nokia Lumia phone, go to Settings > access point, and select your network operator.
3. Confirm with your network operator that you have an active mobile data subscription (access to internet) on your SIM card.
4. Enable the cellular data connection on your phone, go to Settings > cellular and switch Data connection to On.
5. Check that your data roaming is activated when you are not in your home network, go to Settings > cellular and select data roaming options.
6. 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.
7. If you have Multi-SIM (two SIM cards of the same mobile phone number), note that SMS and MMS can only be received on your assigned “primary” SIM card.
8. If you have a known Wi-Fi network running in the background, this can trigger the Wi-Fi network connection to be established. In this case, tap Settings > WiFi and switch WiFi networking temporary off. 

The previous actions usually solve your problem. If it does not help, insert your SIM card in another device and retry. If it is working in another device, contact your network operator for Internet and MMS settings reconfiguration or you may need reset the phone to factory settings (Settings > about > reset your phone).

The phone notifies you if the phone memory is getting low. To free phone memory you have the following options:

• Move data that you want to keep to an alternative memory (mass memory or memory card, if available) or to a compatible computer.
• Remove data you no longer need.

Use File Manager or the respective application in your phone to remove data or to move data to alternative memory as described in the user guide. Typically you first mark files to be removed or moved and then you select the corresponding option (Delete or Move to folder).

Use Nokia Suite to move data to a compatible computer.

To maximize free spaces to your phone memory, you can remove or move the following:

• Messages from Inbox, Drafts and Sent folders in Messaging
• Retrieved e-mail messages from the phone memory
• Saved Web pages. Clear the web browser cache to free some phone memory (e.g. select Options > Clear privacy data > Cache).
• Saved images, videos, or sound files (in Gallery, Photos, Videos or Music player)
• Contact information (in Contacts)
• Calendar notes (in Calendar)
• Downloaded application packages
• If there are applications which are not needed any more, uninstall them with Application Manager
• Any other data that you no longer need

If you are deleting multiple items and any of the following notes are shown: Not enough memory to perform operation. Delete some data first or Memory low. Delete some data, try deleting items one by one (starting from the smallest item). After deleting data, restart (power off/on) your phone.

Tips: Use the memory card or mass memory instead of phone memory in the Camera or other applicable applications in case the selection is available (e.g. via Options > Settings > Memory in use).

1. Restore the original factory settings on your Nokia phone. For information on how to do this, see your Nokia phone's user guide (your personal data is not deleted in the reset). Retry.
2. Contact your network operator to check that Internet browsing (data connection) is included in your service contract (SIM card). Also verify that roaming is supported when you are not within your home network.
3. Make sure your Nokia phone is running the latest software. For downloads and assistance, go to ýour local Nokia website's support page.

This error is sometimes caused by a corrupted MDataStore.db3 file used by Nokia Music Player. This file will need to be deleted with Nokia Music Player closed. Then open the player and the datastore file will be rewritten by the application:

Close Nokia Music Player and delete the MDataStore.db3 file:

*The MDataStore.db3 file is also used by Nokia Suite to store user data, such as: SMS, calendar entries and contact information. Therefore, users of Nokia Suite are advised to backup any user data before removing the .db3 file.

- Vista and 7 C:\Users\<user>\AppData\Local\Nokia\Nokia Data Store\DataBase\MDataStore.db3
- XP C:\Documents and Settings\<user>\Local Settings\Application Data\Nokia\Nokia Data Store\DataBase\MDataStore.db3

Both of these locations are in hidden folders.  So, to view them users will need to: 
Open Windows Explorer > Tools > Folder Options > View > Show Hidden Files and Folders

Once Nokia Music Player is opened again the MDataStore.db3 file will be rewritten to this folder.

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.
 

Contact your operator immediately:

1. To block your SIM card.
2. To block your Nokia device (HW, IMEI code) to prevent it being used in the operator networks with any other SIM cards.  Note that not all operators provide this service (blocking device).

Note: Nokia customer support doesn't have the possibility to block the SIM card or the device, or track a stolen device.

To minimize the risks caused by the theft or loss of the device, there are some security features which you can enable in your device:

1. If your Nokia device supports phone autolock or security keyguard and you have turned it on, the phone cannot be accessed without entering a correct lock code. When enabling the autolock feature, it is important that you change the default lock or security code (12345) to your own lock code and don't forget this code.
2. Some Nokia devices support also remote locking. If you have enabled this feature, you can send a pre-defined text message to your device and lock it remotely. The device is locked if it is switched on and has your SIM card in it.

Note that the phone autolocking and remote locking cannot be enabled after the device has been lost, so it is important that you enable these security features already when taking the device in use.

These simple steps can help in a majority of cases.

Restart your phone

For phones with removable battery:
1. Switch your phone off
2. Remove the battery.
3. After a few seconds, put the battery in and switch your phone on.

For phones with non-removable battery:
1. Press and hold the power button until the phone vibrates and switches off.
2. Switch your phone on again.

Reset the settings

Restore the original factory settings as instructed in your phone's user guide.

Update the software

Make sure your phone is running the latest software. For downloads and assistance, go to your local Nokia website's support page.

Select Menu > Settings > Rest. factory sett. (or Reset device or Restore factory sett. or Rest. fact. sett.).

1. To reset only preference settings, but keep all personal data, such as contacts, messages and media file, select Restore settings only (or Restore sett. only or Settings only).
2. To reset all preference settings and delete all personal data, select Restore all (or All).

3. Enter the security code before the restore. If you have never changed your security code, then enter the default code 12345. If your phone still requests a security code or if you have forgotten it, please bring it to the nearest Nokia Care point for inspection.
