I don't use my cell phone for frivolous things. I rarely use my cell to "chat" but I use it for my patients, my agency and my family.
My job requires me to be available to my agency and my patients at all times. For what I do, a land line wouldn't work. I used to do this years ago, before I could afford a cell phone and it was really difficult. If I couldn't find a patient's house, I'd have to find a pay phone and then call them or the agency and get directions, if I was late, same thing. I would need to give my family my patient's home phone number in case of emergency, and that wasn't fair to my patients. Also, my agency can text or call me for last minute appointments with patients.
I also like my cell so I can keep in touch with my children. A few weeks ago, I had to stay with a sick patient. I had to call one child (an adult) to make sure she was home to let my youngest child home, then I got a call from the child at school who had missed the bus. Then she had to call her sister, from her cell phone for a ride home (as I couldn't leave a sick patient until her reinforcements arrived with the medications.) Then, I knew my youngest child was safe, via my cell phone, while my patient and I were on HER phone with her doctor.
It would be difficult to use my patient's home phones to get in touch with the agency or my family, or other patients.
It's a gift to my work and my family life.
