How do I resolve a phone call problem?

• Check that you have not configured your device to use the 4G network (LTE) or 3G network (UMTS) only; it is better to use the dual mode (2G/3G) or triple mode (2G/3G/4G).

• Check that your phone is not in Offline mode or Airplane mode.

• Restart your phone and check again.
• Restart your phone using the original settings, as explained in the user guide. Check again (back up the data saved in the phone before you try this measure).
• If the signal strength is still weak in a given area, it is possible that reception is poor in this location

• Check that the phone is switched on and that the network signal strength is adequate.

Signal strength is shown by the signal bar on your phone's screen. The number of bars increases in proportion to signal strength, and reduces if the signal becomes weaker.

To increase signal strength, change your location slightly or move closer to a window if you are in a building.

If the phone is set to Airplane mode or Offline mode, it is quite normal for you not to receive any calls. Change the mode by selecting General or Normal, as described in the user guide.

• Check that the call divert function has not been activated.
