What's the best cellphone for the disabled?

Wilbur is a paraplegic and is looking for an affordable cellphone. Leo says that his mom got her cellphone through a program at AARP for about $10 a month. Wilbur wants a better one for emergencies, though.

Leo says that SafeLink Wireless has free cell service for MedicAid participants. If all Wilbur wants is a phone to call 911, all cellphones are required to have 911 service, even if they don't have a wireless service attached to it.
