This works because the Cellular Telephone Industries Association (CTIA) requires text message programs to acknowledge and act on phone users' requests to opt-out or end correspondence when told to.
To deal with a suspicious text message, here are some questions you can ask yourself based on information from the Federal Trade Commission (FTC).
- Does it ask you to give any personal information?
- Does it claim that you have a fake invoice for a transaction you believe you didn't authorize?
- Does it claim that you have a package delivery when you haven't ordered anything?
See the Federal Trade Commission's website for more ways that scammers target unsuspecting people via text. In the meantime, here's a rule of thumb you should always remember:
If you believe that the information in the text message is true, always contact the company using a phone number or website that you’ve confirmed is authentic. Never use the contact information in the text message.
If you have an iPhone, you can report junk iMessages by using the Report Junk link under the message.
On an Android phone, you have to tap and hold the message you want to report and follow the prompts to Tap Block > Report Spam > OK.
