Recently I had a cellphone that I used mainly for communicating with my contacts by text message. Only when it had to be sent for repair did I realize how beneficial it was.
Particularly valuable to me was the ability to group contacts together so that when I wanted to send the same message to multiple persons away it went to all in a grouop at the touch of one button.
Just as with sending so with receiving. Anyone in the group replying automatically sends to everyone.
Of course some things are confidential but this is taken care of by being able to arrange a single other.
I have a cellphone again and made this post as part of my exuberance. All residents can benefit from having a cellphone.
