The mobile phone is folded very small, and comes without calling for weeks from the battery and when the battery needs to be recharged, you will be on of the phone by 1/2 stündig repeated discreet reminder, if need about 1 day, or even longer reloading recalls. Because the device is so small, it does not bother in his pocket.
The only thing that is slightly annoying incomplete manual that leaves many unanswered questions unanswered.
