Promotional SMS can be informative or annoying. If you no longer wish to receive promotional SMS from a company, you can cancel them.
Be cautious with promotional SMS that ask you to send a return SMS or call a telephone number. This applies, in particular, if you do not know the company behind the promotional SMS.
