Notes
San Marino (SM) has specific guidelines for SMS sending that must be strictly followed. Alphanumeric sender IDs are generally supported, while numeric sender IDs are usually not allowed unless a two-way service is used. Generic sender IDs such as INFO, SMS and NOTICE are prohibited; therefore it is recommended to use a representative brand or company name to ensure delivery.
When it comes to marketing traffic, it is important to obtain consent from users before sending messages. There are strict restrictions on the content of messages; person-to-person (P2P) traffic is not allowed, and no political, religious, unsolicited advertising or gambling-related content may be sent. In addition to these guidelines, our Acceptable Use Policy applies to all messages sent to San Marino.
It is important to note that the rules for SMS broadcasting may change and we strive to keep the information updated and correct. For any questions or need for assistance, it is recommended to contact our experts.
