This cell phone I bought for my blind and pflegebedürtige mother. I was looking for a cell phone, with an emergency call button outside that a programmable number (namely my number) automatically calls I pick up and the need to open in order then to speak. Since this phone these actions properly performs from my side full marks. The programming was simple and understandable. For instructions on how I did not need to read. I'm not at home, my mother needs when necessary only to press the emergency button and put the phone aside. The phone tries to reach me 5 times until I pick up. My mother is then free to communicate with me and I can respond accordingly. Would I buy for this purpose again !!
