I'm in sales and I don't use mine that much. I have Verizon 1,000 minutes a month, free nights and weekends, roaming (I don't know $$$ never roam), texting which I do maybe a dozen times a month. Costs me about $50 a month. I could pay an extra $10-$20 a month to get internet access but I don't need that. I don't get important enough emails that they cannot wait until I can get to my desktop.
I don't get how people run up these $200 phone bills, put the damn things down! You could get a nice car for that!
I think last month I used 500 minutes, 300-400 were probably for work. I do must of my calls in the office on the land line, the cell is mostly quick, out of the office calls.
