The Data Plans and Features MAY NOT be used for any other purpose. While most common uses for Intranet browsing, email and intranet access are permitted by your data plan, there are certain uses that cause extreme network capacity issues and interference with the network and are therefore prohibited. Examples of prohibited uses include, without limitation, the following: Example

(iii) "auto-responders," "cancel-bots," or similar automated or manual routines which generate excessive amounts of net traffic, or which disrupt net user groups or email use by others; Cant find any examples to this

(viii) software or other devices that maintain continuous active Internet connections when a computer's connection would otherwise be idle or any "keep alive" functions You cant ping, unless they adhere to AT&T's data retry requirements, which may be changed from time to time.
