Cell phone plans
You sign a contract to get a free or discounted phone. You do not get unlimited voice or unlimited data. You pay big bucks for a cell phone plan you cannot change. You only get rewarded with an upgraded cell phone (that you may not really need) But now you are required to be locked into another plan for 2 to 3 years. You might go with prepaid cell phone plan but most of the big cell companies give you less coverage with a prepaid plan and charge you more for a smart phone.
