Sending SMS

Service and promotional SMS

A service message responds to the recipient’s action: a login code, an order status, a receipt, a booking reminder. Everything else counts as promotional. The mobile operator decides the template type during review.

How they differ

  • Price. Service and promotional SMS have different rates — see the Pricing tab.
  • Sending time. Promotional messages may only be sent from 9:00 to 18:00. A promotional campaign that falls on night hours waits for the morning and continues automatically.
  • Consent. Promotional messages go only to recipients who agreed to receive them.

What is prohibited

Advertising of alcohol, tobacco, gambling, financial pyramids, and campaigns to purchased databases.
