that vary based on the time of access will be determined based on the location of the network equipment providing service and not the location of your Device or your Device’s area code (if applicable). Push-to-Talk Charges: Charges for push-to- talk calls are billed to the person who starts the call and calculated by multiplying the duration of the call by the applicable rate and number of participants. You’re charged at least 6 seconds of airtime for each call you start; subsequent communications in the same call are rounded up to and billed to the next second. Time begins when you press any button to start a push-to-talk call and ends approximately 6 seconds after completion of a communication 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,
