Troubleshooting and error codes
| Problem/Display Message | Possible Cause & Solution |
|---|---|
| The display shows SIM failure | Check that the SIM card has been inserted correctly. If the problem persists, your SIM card may be damaged. Contact your operator. |
| When attempting to use a feature in the menu, the display shows NOT ALLOWED | Some features are network dependent. They are only available, therefore, if the network or your subscription supports them. Contact your operator for detailed information on this subject. |
| The display shows INSERT YOUR SIM CARD | Check that the SIM card has been inserted correctly. If the problem persists, your SIM card may be damaged. Contact your operator. |
| The autonomy of your phone seems lower than indicated on the user guide | The autonomy is linked to your settings (e.g., ringer volume, backlight duration) and the features you use. To increase the autonomy, and whenever possible, you must deactivate features you do not use. |
| Your phone doesn't work well in your car | A car contains many metallic parts that absorb electromagnetic waves which can affect the phone's performance. A car kit is available to provide you with an external antenna and enables you to make and receive phone calls without handling the handset. Check with the local authorities whether or not you are allowed to use the phone while driving. |
| Your phone is not charging | If the battery is completely flat, it might take several minutes of pre-charge (up to 5 minutes in some cases) before the charging icon is displayed on the screen. |
| The picture captured with the phone camera is not clear | Make sure that the camera lens on both sides is clean. |
