session and is then charged to you based on the terms of your Services. 

Depending on your Services, usage may be charged against an 

allowance or on a fixed price per kilobyte. Usage charges may be 

rounded up to the next cent at monthly or other intervals. In certain 

instances, you may not know that your session has not ended. As long 

as your device is connected to our network, you will incur data usage 

charges. You will be charged for all data directed to the internet 

address (or "IP address") assigned to your device, regardless of who 

initiates the activity or whether your device actually receives the data. 

This includes, but is not limited to, the amount of data associated with 

the particular information/item (e.g. game, ringer, email, etc.), 

additional data used in accessing, transporting and routing this 

information/item on our network, data from partial or interrupted 

downloads, re-sent data, and data associated with unsuccessful 

attempts to reach websites or use applications. Based on these and a 

number of other factors (e.g., the specific application, network 

performance, etc.) data used and charged to you will vary widely, even 

for the same activity. Estimates of data usage – for example, the size of 

downloadable files – will not be accurate or a reliable predictor of 

actual usage. Your invoice will not separately identify the number of 

kilobytes attributable to your use of specific sites, sessions or services. 

Taxes and Surcharges.

We invoice you for taxes, fees and other 

charges levied by or remitted directly to federal, state, local or foreign 

governments including, without limitation, sales, gross receipts, 

Universal Service, use, and excise taxes. If you claim any tax 

exemption, you must provide us with a valid tax-exempt document. 

Tax exemptions are not applied retroactively. We also invoice you for 

surcharges that we collect and keep to pay for the costs of complying 

with government programs such as number pooling and portability, 

and Enhanced 911 service; these charges are not the taxes nor 

government imposed assessments. 

Invoicing & Payment.

 Invoicing cycles and dates may change from 

time to time. Monthly recurring and related charges for Services are 

generally invoiced one invoicing cycle in advance. Other charges are 

invoiced soon after they are incurred. Most usage is generally applied 

to the invoicing cycle in which they are incurred, but in some 

instances may be applied to subsequent invoicing cycles. You are
