Don't be afraid to shop around for a new cell plan just because of your contract. All cell phone companies now prorate termination fees, which makes it less expensive to switch carriers -- do the math and see if a better mobile (and mobile data) plan is worth the termination fee.
Tip Five: Premium Text Messages
Unlimited mobile data plans do not include premium texts -- these are the fees charged to your mobile account when you download a ringtone, sign up for a daily mobile horoscope service, vote on a TV show contestant, or donate to the Haiti relief fund.
Premium text messages can cost a bundle and parents should make sure that these services are blocked on kids phones. Parents can call the cell phone company and instruct it to put limits on premium text messages for their children.
