Regulations and Best Practices
Gambling, adult & betting content is not allowed. In addition according to act No. 480/2004 Coll., for Certain Information Society Services (effective from 1 July 2017) the sending of messages for the purpose of spreading a commercial communication is prohibited if:
- Message is not clearly identified as a commercial communication
- The identity of the sender (brand) is concealed or hidden
- Message is sent without a valid address to which the addressee may directly and effectively opt out
This regulation is valid for any A2P SMS traffic, but foremost applied and enforced on 2-way (Long Number) communications where the brand is not directly visible as sender name.
Clients that send promotional traffic should start the message with "OS:". This means "obchodni sdeleni" which translates to "commercial communication".
