How to Block Bulk SMS - Stop Promotional SMS - Uwazii MOBILE

Bulk SMS Character Count, Safaricom

On 4th August 2015, Safaricom introduced a new messaging regulation that requires all promotional bulk SMS messages to provide a means of opt-out.

To comply with this regulation Uwazii MOBILE through Safaricom supports a USSD code which a subscriber can dial and they will be provided opt-out to STOP receiving further messages from an alphanumeric Sender ID.

To inform the subscribers of the possibility of opting out we automatically add an opt-out option to all messages that are terminated through our gateway towards the Safaricom network. We automatically append a 13 character long suffix 'STOP*456*9*5#' at the end of every bulk SMS message. It is important to take this into consideration when calculating the length of your message.

In case you have any technical concerns please contact us for further clarification of the regulations.
