Mine is used only for phone calls. I have had the provider turn off text functions as I was weary of paying for dumb arse texts that people would send me. I find it much easier to talk than mash a ton of buttons to send a text.
When I was a district manager I had a phone growing out my ear and ran up over 3000 minutes a month. My current plan is 450 mins/mo. and I think my highest usage was 100 minutes. I do burn up the free M2M calls though.
Sometimes it's nice to be "old school"!
