to which no participant responds. Subsequent push-to-talk communications are considered new calls. Charges apply for the entire period of time the push- to-talk call is connected to our network. Depending on your plan, nationwide, international, or group push-to-talk calls may use the local push-to-talk minutes

in your plan and result in additional or different charges. Responses to call alert transmissions are treated as new push-to- talk transmissions even when responding within 6 seconds of receiving the alert. Push-to-talk billing methods are subject to change as we introduce new push-to- talk Services.

Data Usage: Unless we specifically tell you otherwise, data usage is measured in bytes, kilobytes, megabytes, and gigabytes—not in minutes/time. 1024 bytes equals 1 kilobyte (“KB”), 1024 KB equals 1 megabyte, and 1024 megabytes equals 1 gigabyte. Bytes are rounded up to KB, so you will be charged at least 1 KB for each data usage session (“data session”). Rounding occurs at the end of each data session, and sometimes during a data session. Depending on your data Services, usage may be charged against an allowance or on a fixed price per KB, and you may be subject to limitations on the amount of data usage. If you are charged on a fixed price per KB, any fractional cents will be rounded up to the next cent. You are charged for all data directed to your Device’s Internet address, including data sessions you did not initiate and for incomplete transfers. As long

as your Device is connected to our data networks, you may incur data charges. Examples of data for which you will be charged includes the size of a requested file or Data Content (game, ringer, etc.);
