Depending on your Services, charges for additional services may include operator and directory assistance, voicemail, call forwarding, data calls, texts, and Web access. If you (the account holder) allow end users to access or use your Devices, you authorize end users to access, download, and use Services. You may have the opportunity to purchase Services on a subscription basis where we assess subscription charges that allow you access to the Services and/or provide you a certain amount of use of the Services for a defined period of time. Depending on your Service, certain types of subscription charges may be assessed automatically upon activation and automatically assessed for subsequent subscription periods. Subscription Services offered on a recurring basis do not end until terminated by you or us. Subscription charges for recurring Services occur at the beginning of each bill cycle. Information regarding your bill cycle for subscription Services will be provided when you order the Services. For Services offered on a per- day basis, you will generally be charged for use before or at the time of use. In certain instances, we may charge you at some point after you use the Services. Unless otherwise disclosed, Services offered on a per-day basis end 24 hours after Service is initiated.
