Cell phone family plans are an excellent way to save money on your monthly phone bill. Usually, cell phone service providers will provide a discount for extra lines added to a family account. You may even be eligible for discounts on multiple phones when you apply for these plans. Family plans are available through a number of different cell phone service providers, including the top companies such as AT&T, Verizon, Sprint, and others. By sharing the cost of your cell phone bill with other family members, you will be able to expand your monthly budget and save money.
