Excerpt from service specific terms:
UNLIMITED USE DOES NOT MEAN UNREASONABLE USE. To ensure that all customers have access to reliable services provided at a reasonable cost, you may not use our service in a manner that interferes with another Boost Mobile customer's use of our service or disproportionally impacts Boost Mobile's network resources. Prohibited Uses: Boost Mobile services are provided solely for live dialogue between, & initiated by, two individuals for personal use & as otherwise described in this policy. Boost Mobile services may not be used for any other purposes, including, but not limited to, conference calling, monitoring services, data transmissions, transmission of broadcasts, transmission of recorded material, interconnection to other networks, telemarketing, autodialed calls, other commercial uses, or other connections that do not consist of uninterrupted live dialogue between two individuals. If your plan includes data services, such services are provided solely for purposes of web browsing, messaging, & similar activities. Examples of Prohibited Use of our data services include but are not limited to use thereof (1) with server devices or host computer applications, or other systems that drive continuous heavy traffic or data sessions, including, but not limited to, disproportionate Web camera posts or broadcasts, automatic data feeds, automated machine-to-machine connections, peer-to-peer (P2P) file-sharing applications broadcast to multiple servers or recipients such that they could enable "bots" or similar routines; (2) as a substitute or backup for private lines or frame relay connections; (3) to send or receive unusually high numbers of messages (4) to engage in atypical web usage behaviors; (5) for tethering your device to a personal computer or other hardware; & (6) for any other reason that, in our sole discretion harms our network. We will presume you are engaging in a Prohibited Use, in violation of these terms and conditions, if you are placing an abnormally high number of calls, or repeatedly placing calls of unusually long duration (as compared to other customers on the same service plans), or if your usage is harmful or disruptive to Boost Mobile's systems or services. If we determine, at our sole discretion, that you are using an unlimited service in violation of the Boost Mobile General Terms & Conditions of Service, these Terms of Service, or in any other manner that we deem to be unreasonable or excessive, then we may terminate individual calls, or, after providing notice to you, terminate your service, decline to renew your services, or offer you a different service plan with no unlimited usage components.
