Im an electrician, and I have to call customers all the time to make appointments. And if they dont answer I send them a text with why I call and that they could call me to make an appointment.

What I really want is a easy way to have insert a kind of standard text. Prefferably a set of texts to choose from and to create your own.

(I got big fingers and presses wrong letter all the time so texting for me is a hassle)
