SMS broadcast

Legal situation

SMS broadcast - legal situation

The transmission of promotional SMS is legally not allowed without the formal agreement by the mobile phone owner. Court decisions on commercial e-mails and faxes can be transferred to commercial SMS according to legal literature. Unrequested addresses are not allowed and can lead to a costly warning. The usage is allowed only if a formal agreement by the recipient is given.

Tips for gaining formal agreements



Proceed in several steps. Send out a letter, which enables the recipient to give his agreement for receiving your SMS broadcast. 
Or collect agreements on trade fairs.


Inform the recipient about the SMS broadcast and its benefits. (Special offers). A combined prize competition with attractive winnings increases the rate of returns.

Consider the aspects on the right side in order to increase your chances of success.

Consider these aspects

  • Ask simultaneously for the recent, valid mobile phone number (even if you already have one).
  • Let the recipient confirm their agreement formally.
  • Let your recipient know that they can revoke their consent at anytime.

"Our employees are on the road throughout Germany, partly even in Europe. A regular coordination is essential here. We are completely independent with GTC central meeting: all participants are dialing themselves in via telephone. It doesn’t matter, where the participants are. Even the dial-up from abroad happens at low costs, due to international access numbers."
