Unsolicited or SPAM Messages

Despite continuous improvements to the technology, wireless companies have not found a way to stop unsolicited or SPAM Text Messages. There are a few solutions out there that each of the companies allow. Here are the steps you can take with the 4 largest wireless companies to help stop unsolicited text messages.

Verizon Wireless

At vtext.com if you go to the preference section you can set up Spam Blocking for no charge. It allows you the option to:

  • block all messages originating from the web
  • block up to 15 specific email addresses and/or web domains
  • only allow email messages sent to your Vtext.com nickname
  • block messages sent from all email addresses
  • See: http://support.vzw.com/information/blocks_comparison.html
  • You can also call customer service. You should contact customer service if you need to have a charge for the unsolicited text removed.

AT&T Mobility

AT&T does not have a method for you to block incoming text from wireless numbers unless you sign up for Smart Limits at $4.99 per month.  AT&T suggests that you should reply with the word STOP to unsolicited text messages to prevent further messages particularly if the message is from a shortcode.  Otherwise you should contact AT&T Customer Service.
