may not be able to give you advance notice about how such changes might affect you. Except as prohibited by law, we may also, at our discretion, require you to pay regulatory and administrative fees to recover our costs of complying with regulatory mandates and Universal Service fees or similarly imposed charges. Any customer who is eligible for an exemption from any tax or fee must provide us with a valid and properly executed tax-exempt certificate which will be verified by us. Any tax exemption applies only after the date we receive the certificate from you and have verified your eligibility for the exemption. Roaming and Roaming Charges You are "roaming" whenever you make or receive a call using a transmission site outside the United States and Canada. There may be extra charges (including charges for long distance, tolls, or calls that don't connect) and higher rates for roaming calls, depending on your calling plan. 76 Your Bill/Statement Your bill/statement is our notice to you of your fees, charges and other important information. You should read everything on your bill/statement. We bill usage charges after calls are made or received. We bill access fees and some other charges in advance. How We Calculate Your Bill Your bill reflects the fees and charges in effect under your calling plan at the time they are incurred. You can dispute your bill, but only within 180 days of receiving it. You must still pay any disputed charges until the dispute is resolved. Depending on your rate plan, charges for calls may be based on the location where you are and the time of day when the call took place. Rates do not apply to credit card or third party operator-assisted calls, which may be required in certain areas. The length of a call will be rounded up to the next full minute. Charges start when you first press YES to dial a call on outgoing calls, and when the call rings on an incoming call. 77
