Looking to earn a little pocket money? Convince your family or friends to sign up with Sprint and the carrier will reward you with a $50 Visa Debit Card for each line that is activated as a result of your arm-twisting and pleading. You are limited to receiving no more than $600 in debit cards over a 12 month period. The person signing up with the pin-dropping network receives a $25 Visa Debit Card for each line they activate. For the first time, Sprint will give out the rewards for those who sign up for mobile broadband cards. So start pestering your brother, sister, Mom, Dad, co-workers and friends to sign up with Sprint. Your wallet or purse will thank you.
