Cricket
Prohibited Network Uses. To ensure the activities of some users do not impair the ability of our customers to have access to reliable services provided at reasonable costs, you may not use our services in a manner that is unlawful, infringes on intellectual property rights, or harms or unduly interferes with the use of Cricket's network or systems. Cricket reserves the right, without notice or limitation, to limit data throughput speeds or quantities or to deny, terminate, end, modify, disconnect, or suspend service if an individual engages in any of the prohibited voice or data uses set forth in the Agreement, Fair Use Policy, Acceptable Use Policy, detailed below or if Cricket, in its sole discretion, determines action is necessary to protect its wireless networks from harm or degradation. Examples of prohibited voice uses: Cricket voice services are provided solely for live dialogue between, and initiated by, individuals for personal use and as otherwise described in this policy. Cricket services may not be used for any other purposes, including, but not limited to: monitoring services, transmission of broadcasts, transmission of recorded material, telemarketing, autodialed calls, other commercial uses, or other connections that do not consist of uninterrupted live dialogue between individuals. Examples of prohibited data uses: Cricket data services are provided solely for purposes of web surfing, sending and receiving email, photographs and other similar messaging activities, and the non-continuous streaming of videos, downloading of files or on-line gaming. Our data services may not be used: (i) to generate excessive amounts of Internet traffic through the continuous, unattended streaming, downloading or uploading of videos or other files or to operate hosting services including, but not limited to, web or gaming hosting; (ii) to maintain continuous active network connections to the Internet such as through a web camera or machine-to-machine connections that do not involve active participation by a person; (iii) to disrupt email use by others using automated or manual routines, including, but not limited to "auto-responders" or cancel bots or other similar routines; (iv) to transmit or facilitate any unsolicited or unauthorized advertising, telemarketing, promotional materials, "junk mail", unsolicited commercial or bulk email, or fax; (v) for activities adversely affecting the ability of other people or systems to use either Cricket's wireless services or other parties' Internet-based resources, including, but not limited to, "denial of service" (DoS) attacks against another network host or individual user; (vi) for an activity that connects any device to Personal Computers (including without limitation, laptops), or other equipment for the purpose of transmitting wireless data over the network (unless customer is using a plan designated for such usage); or (vi) for any other reason that, in our sole discretion violates our policy of providing service for individual use. Unlimited Use Plans. If you subscribe to rate plans, services or features that are described as unlimited, you should be aware that such "unlimited" plans are subject to these Cricket Prohibited Network Uses.
Data: Services are not available with all Cricket phones. The amount of data transmitted over our network is measured in kilobytes (KB), megabytes (MB) or gigabytes (GB). Unless specified otherwise 1024KB equals 1MB. 1024MB equal 1GB. Usage is calculated on a per kilobyte, megabyte or gigabyte (depending on your rate plan) basis and is rounded up to the next whole kilobyte, megabyte or gigabyte. Rounding occurs at the end of each session or each clock hour and at which time we deduct accumulated usage from your plan. You are responsible for all data activity from and to your device, regardless of who initiates the activity. Estimates of data usage will vary from actual use. Your bill will not separately identify the number of kilobytes, megabytes or gigabytes attributable to your use of specific sites, sessions or services used. Premium content (games, ringtones, songs, etc.) priced separately. Services are not available for use in connection with server devices or host computer applications, other systems that drive continuous heavy traffic or data sessions, or as substitutes for private lines or frame relay connections. Except with phone-as-modem rate plan orfeature, you may not use a phone (including a Bluetooth phone) as a modem in connection with a computer, PDA, or similar device. We reserve the right to deny or terminate service without notice for any misuse or any use that adversely affects network performance.
Straight Talk
Accessing Mobile Web Services and Purchasing Web Content: Unless you are on an Unlimited Service Plan, each time you access the Mobile Web through your Straight Talk phone’s browser, your Mobile Web Access balance in your Straight Talk phone will be debited for that usage (“Access Charges”
. Access Charges are deducted in full kilobyte increments. Access Charges begin when your Straight Talk phone connects to the Mobile Web Service. This should occur after you open your browser, send or receive a multimedia message (for example, a digital photo), initiate a content download, or if Mobile Web Access is initiated for any other purpose. Access Charges end when the connection to the Mobile Web Service terminates. This should occur shortly after you close your browser, successfully receive or send a multimedia message, after a successful content download or when you exit a Mobile Web session. The Mobile Web Access duration and the related Access Charges are NOT determined from the exact moment you press a button on your Straight Talk phone to open or close the browser.
Unless you are on the Unlimited Service Plan, there is always an Access Charge associated with accessing the Mobile Web, sending or receiving a picture message and downloading content. Total Access Charges will depend on the size of the content and the actual time it takes to download or transmit the content or multimedia message. Any Web Content you buy and download may only be used or viewed on the Straight Talk phone for which the Web Content was purchased and cannot be transferred to any other device, including a new or replacement Straight Talk phone. Web Content purchases are non-refundable and non-transferable.
Availability, Interruptions and Discontinuation of Mobile Web Service: Straight Talk does not guarantee the availability of Mobile Web Service in your network coverage area at any time and reserves the right to modify, suspend, interrupt, discontinue or permanently cancel Mobile Web Service, or portions thereof, without notice. Mobile Web Service is not available outside of your coverage area. Straight Talk is not responsible and will not be liable for any modifications, interruptions or discontinuation of Mobile Web Service or for your failure to receive any purchased Web Content. If Mobile Web Service, or any part thereof, is modified, interrupted, discontinued or cancelled, Straight Talk will NOT issue any refunds or reimburse you for any remaining used or unused Services. If you cancel, or attempt to cancel a web download, subscription purchase or a multimedia message in progress, or if this process is otherwise interrupted through no action on your part, Mobile Web Access usage may nevertheless be deducted. If the Straight Talk Mobile Web Services are unavailable and you have opened your browser, you will be deducted usage even though you will not be able to view or utilize the Mobile Web Service.
T-Mobile
11. * Data Plans and Other Features. You will be charged for data usage on a pay per use basis unless you are required to maintain a data plan ("Data Plan") as part of your Service, or as otherwise provided by your Rate Plan or prepaid data pass. Permissible and Prohibited Uses: Your Data Plan is intended for Web browsing, messaging, and similar activities on your Device and not on any other equipment. Unless explicitly permitted by your Data Plan, other uses, including for example, using your Device as a modem or tethering your Device to a personal computer or other hardware, are not permitted. Other examples of prohibited uses can be found in Section 18. Protective Measures: To provide a good experience for the majority of our customers and minimize capacity issues and degradation in network performance, we may take measures including temporarily reducing data throughput for a subset of customers who use a disproportionate amount of bandwidth. In addition, if your total usage exceeds 5GB (amount is subject to change without notice; please check T-Mobile's T&Cs on
Unsupported Browser for updates) during a billing cycle, we may reduce your data speed for the remainder of that billing cycle. If you use your Data Plan in a manner that could interfere with other customers' service, affect our ability to allocate network capacity among customers, or degrade service quality for other customers, we may suspend, terminate, or restrict your data session, or switch you to a more appropriate Data Plan. We also manage our network to facilitate the proper functioning of services that require consistent high speeds, such as video calling, which may, particularly at times and in areas of network congestion, result in reduced speeds for other services. Additionally, we may implement other network management practices, such as caching less data, using less capacity, and sizing video more appropriately for a Device to transmit data files more efficiently. These practices are agnostic to the content itself and to the websites that provide it. While we avoid changing text, image, and video files in the compression process when practical, the process may impact the appearance of files as displayed on your Device.
So yeah Boost Mobile is evil as any other carrier in the U.S. for having ToS.
