I plan to buy a 3G phone for my mom, so the most important is the phone (ringtone) must be loud so that she could hear and know there's an incoming call, the best is the word also quite big, easy to use

brand: NOKIA, SAMSUNG, SE
Spec: clear 3G, loud and clear ringtone, big words easy for her to see the msg or number
budget: fulfill the specs and as cheap as possible

am my requirements too hush? thanks in advance
