#49 Getting Dollars From Dropped Calls
Many moons ago, Sprint used to have a 1-800 number that you would call for drop call credit (.50) and it could be called up to 20 times a month.
You could also buy referrals for Sprint from eBay for dollars and you would get a nice referral credit.
For two years, my cell phone bill was less than $5 every month. Man, those days were nice.
