What is Premium SMS?
Premium SMS (PSMS for short) is the denomination for text messages with a set tariff that is applied to an incoming or outgoing message. The additional tariff is applied to a consumer's mobile phone bill, or debited directly from a pay-as-you-go card. This technology makes it possible to use SMS as a payment method.
The most common way of payment requires the user to send a message to a national short code (in Sweden for instance, these are 5 digit numbers starting with 7, e.g. 72456). After having sent a message, the user is then debited the set tariff and can receive their ring tone, coupon, code or get access to a service or product, with the action or product delivered by SMS, alternatively a receipt delivered by SMS.
