How to Stop Suspicious Messages on Your AT&T iPhone

Receiving suspicious text messages on your AT&T iPhone can be both annoying and potentially harmful. Fortunately, there are several steps you can take to block and report these messages, enhancing your device's security.

Apple provides a built-in feature to filter messages from unknown senders:

  1. Open the Settings app.
  2. Scroll down and tap on Messages.

  2. AT&T will reply, asking for the phone number of the sender.

Messages forwarded to 7726 are free and do not count toward your text plan. (att.com)
