The mobile phone I bought for our grandmother, because of the emergency call button. If it works great. Long press and then the emergency number angerufen.Wenn the person will answer the call, it automatically switches to handsfree. Only the phone has, unfortunately, the connection often interrupted since then was nothing more you could press no key and nothing. After about 3 min. Was then again everything OK Just an elderly person would panic. And that can not happen in my opinion an emergency telephone.
