You pay for a product or service available online, the amount of the transaction is added to your phone bill or deducted from your card balance, and you can immediately start using the product or service you have ordered.

You register your number with the website you want to use and pay the membership fee automatically (e.g. one month's access to the film archive or one week's access to a premium account on a social network). The user receives a confirmation that the service has been activated, and then at certain intervals the mobile operator adds a certain amount to his telephone bill (or deducts this amount from the balance in the case of a card phone). In addition, in case of cyclical payment, the user may receive free trial access to the ordered product or service for a period from 1 to 30 days, allowing him to familiarize himself with the service offer. Then, after the free trial period, the user enters the paid user mode and his operator starts charging the cyclic payment at the specified intervals.
