iPhone 6: For Seniors 2014 (2015)
4. Message History
The iPhone 6 has great storage ability which allows it to store almost every message that has been received indefinitely. This helps the senior to keep a record of all incoming and outgoing messages so they can go through them at their leisure. They have the option to clean out after 30 days, but some seniors prefer to keep their records and read them over in their spare time.
