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: (i) server devices or host computer applications, including, but not limited to, Web camera posts or broadcasts, automatic data feeds, automated machine-to-machine connections or peer-to-peer (P2P) file sharing; (ii) as a substitute or backup for private lines, landlines or full-time or dedicated data connections; (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; (iv) "spam" or unsolicited commercial or bulk email (or activities that have the effect of facilitating unsolicited commercial email or unsolicited bulk email); (v) any activity that adversely affects the ability of other people or systems to use either AT&T's wireless services or other parties' Internet-based resources, including "denial of service" (DoS) attacks against another network host or individual user; (vi) accessing, or attempting to access without authority, the accounts of others, or to penetrate, or attempt to penetrate, security measures of AT&T's wireless network or another entity's network or systems; (vii) software or other devices that maintain continuous active Internet connections when a computer's connection would otherwise be idle or any "keep alive" functions, unless they adhere to AT&T's data retry requirements, which may be changed from time to time. This means, by way of example only, that checking email, surfing the Internet, downloading legally acquired songs, and/or visiting corporate intranets is permitted, but downloading movies using P2P file sharing services, web broadcasting, and/or for the operation of servers, telemetry devices and/or Supervisory Control and Data Acquisition devices is prohibited. Furthermore, plans(unless specifically designated for tethering usage) cannot be used for any applications that tether the device (through use of, including without limitation, connection kits, other phone/PDA-to computer accessories, Bluetooth® or any other wireless technology) to Personal Computers (including without limitation, laptops), or other equipment for any purpose.
