If you have limited signal in your property or local area, it is possible your watch may not be able to connect a call in certain areas.
If this is the case you will see "net fail" appear on the screen when placing a call. As signal can be very variable we suggest making test calls in each room of your property (particularly in any vulnerable areas) and places you visit regularly. This will allow you to assess how reliable your watch will be given the limited signal.
Please get in touch with us on 020 3868 5575 (Mon-Fri, 9am-5.30pm) if you are unsure.
