FAQ 5 - Handset Troubleshooting

[-] My calls sometimes break up or are dropped

This can be related to a low network signal strength at either end of the connection.

The dropping of calls can happen for various reasons, including:

  • Moving at high speed

  • Moving between mobile phone cells / towers, it is possible that the next cell does not have capacity for your call (all channels are busy)

  • An Emergency Call in your area can force your call to be dropped as they take priority

  • Network maintenance or upgrades can cause drop outs – Contact your service provider to find out if planned work is occurring in your area

  • Poor coverage - how many signal bars do you have? In areas of poor reception of 1 or 2 bars the handset only has limited network coverage and it is possible that calls will get dropped.
