The TTfone TT970 is a flip phone with an SOS button which sends a text with your location to up to 5 emergency contacts. The phone will then automatically ring each contact in turn until a successful connection is made. The TT970 is fully compatible with hearing aids and automatically connects to them when making or receiving a call. There is an LCD screen on the outside of the phone which displays the caller before flipping it open and the phone comes with a lanyard neck strap option which allows the phone to be worn around the neck to keep it safe and to hand.
