4.1. General Principles

4.1.1. The Service provides services in two modes:
— "Activation" — one-time use of a number;
— "Rental" — use of a number for a selected period.
4.1.2. The service is considered successfully rendered, and the payment final, from the moment the User receives any SMS message on the issued virtual number.
4.1.3. SMSFAST does not provide any warranties regarding the acceptance, processing, or confirmation of the issued number by third-party services (messengers, social networks, marketplaces, websites, and other platforms). The verification and anti-fraud algorithms of such services are entirely outside SMSFAST's control. SMSFAST's liability is limited to the technical provision of the number and the delivery to the User of all SMS messages that were actually received on it.

4.2. "Activation" Mode

4.2.1. Payment is charged only for a successfully received SMS.
4.2.2. If an SMS was not received, the User may cancel the number in the interface — funds are automatically returned to the internal balance.
4.2.3. If the number's validity period has expired and no SMS was received, the transaction is canceled automatically, and funds are returned to the balance.
4.2.4. After successful receipt of an SMS, the transaction is considered completed, and a refund is not possible.

4.3. "Rental" Mode

4.3.1. In this mode, payment is charged for providing a phone number for the selected rental period and ensuring its technical availability throughout the entire period.
4.3.2. Rental is provided for a period from 1 day to 1 year. If necessary, the rental can be extended during its validity period.
4.3.3. During the rental period, the user may receive an unlimited number of SMS messages.

4.4. Important Terms and Limitations

4.4.1. If a telecom operator blocks a number after its issuance and the start of use, a refund is not issued, as the service of providing and ensuring the number's availability has been rendered.
4.4.2. In "Activation" mode, reactivation or extension of a previously issued number is not available. Each number is used once.
In "Rental" mode, extending the rental period may be available; however, SMSFAST does not guarantee the possibility of extension in each specific case, as the further availability of the number depends on external factors beyond the Service's control.
