A sms that incurs a carrier billing charge to a user’s phone bill. Premium SMS is application-to-person technology that is used by businesses that need to bill their consumers using the mobile channel. It works like a standard text message that is “wrapped” in an invoice which gets billed to the consumer’s monthly phone bill or deducted from their pre-pay account. Premium SMS has been the main method of mobile billing in operation across most countries and regions. Under this model, a subscriber is billed either when originating an SMS to a short code requesting the content or when receiving the content on their phone. Content providers have little or no control over their customers’ purchase process and customers have little knowledge of the content providers that they use, since promotion is based around specific content.
