Once you ve paid for these items and services you re done with them. Fixed costs though account for only a part of what it costs to operate a cellular phone. In this chapter we ll look at the other more important expenses what it costs you to use your phone. ONE-TIME NONRECURRING EXPENSES Like the price of purchasing equipment some operating expenses are paid once and never again unless for example you have your phone number taken out of service and then have it restored or if you move to a new cellular service area . These one-time expenses are outlined in the following text. Service Activation Charge This fee typically about 50 is the service provider s charge for making the electronic arrangements for service to your number and for processing the paperwork associated with it. If you suspend service and then request that it be resumed you may have to pay this fee again. This fee is sometimes waived during special promotions. 31 32 THE BILL PLEASE Change Charge If you ask that your service be switched from one phone to another using the same number maybe you just bought a new model you will have to pay for the expenses incurred in making the switchover. Change charges may be around 15. Deposit You will be subject to a credit check when you initiate service for which you will have to grant permission. If your credit is less than perfect you may be asked to pay a deposit to make sure that you can pay your bill. If you choose prepaid service the deposit and credit check may not be necessary. RECURRING EXPENSES Just as with your home phone the use of a cellular phone brings with it certain fixed charges usually the same amount in every billing period. .
