If you have a Data Only plan and use voice service, domestic voice calls will be billed at $0.25/minute. Data sessions may seem inactive while data is actively being transferred, or may seem active when the data is actually cached and data is not being transferred.
A data session is inactive when no data is being transferred. Data sessions automatically terminate after 24 hours. Applications may automatically re–initiate data sessions without your pressing or clicking the SEND or connect button.
Please note that certain applications or widgets periodically send and receive data in the background, without any action by the user, and you will be billed for such data use. Sending or receiving data using a virtual private network (VPN) involves additional VPN overhead for which you will be charged. Verizon Wireless charges you for all data sent or received using our network (including any network overhead and/or Internet Protocol overhead associated with content sent or received), as well as resolution of Internet Protocol addresses from domain names.
