Ask Deemable Tech: How Do I Block Spam Text Messages?

Tap Call

Norma writes, "How do you stop receiving an automated text message? When I got my new phone I started receiving messages from a store telling me about their specials. I've tried visiting the website and 'unsubscribing' but that didn't work. "
We feel you, Norma. Like junk mail and spam email, unsolicited text messages are the bane of our existence. Luckily there are ways to stop them.

If you’re receiving texts from a reputable company, there should be a way to unsubscribe from them through a text. Scroll back through the text messages from that number, and you’ll probably find a message telling you to text the word “STOP,” “QUIT,” “END,” or “UNSUBSCRIBE” to stop receiving texts from them. Different companies use different keywords, but most of the time if you text the word “HELP” to them, they will tell you what other keywords work on their system.

If you’re receiving genuine spam texts from a less than reputable source, the best thing you can do is to not respond. This just lets the scammers know that your number is a good one to keep spamming. Your only choice is to block the number sending you those texts.

How to Block Numbers on iOS
