How to Prevent Spam Text Messages

Posted on the 29 May 2012 by Safegadget_com

Apple iPhone 3GS

The only thing worse than spam in your email box is a spam text message on your cell phone or smartphone. For the last 20 years spam has been clogging up our email, and now it is in full bloom on our phones. Spam Texting needs to stop.

How do Spammers get Phone Numbers?

There are several sources of phone numbers for text message spamming.

  • Internet postings
  • Random phone number generation
  • Auto dialing robo calling

The Dangers in Spam Text Messages

Just like email spam, offers made in unsolicited text messages are full of bogus offers like free iPads, prizes, or gift cards, etc. Clicking on any link or calling a phone number listed in the text message can result in the following:

  • Malware being installed on your phone
  • Unauthorized charges billed to your phone
  • Recurring items added to your phone bill
  • Private information being transmitted to cyber criminals

Fighting Unsolicited Text Messages

The major wireless providers, AT&T, Verizon, Sprint, and T-Mobile try to do everything in their power to prevent these. Each person calling to complain costs them from $5 to $50. The carriers are banding together to create anti-spam and mobile security solutions. Slowly, cell phone technology will rise to the same level as email and anti-spam filters.

The Federal Trade Commission files suit against spammers to help reduce the problems.

You can complain to your wireless carrier and let them know that you are receiving unsolicited text messages by doing the following:

Blocking Text Spam

The major wireless carriers provide Free Spam blocking controls for users. However, there are restrictions.

Here is how you can access the blocking controls online for each carrier:

Verizon Wireless – They offer many different free options to block text spam.

  1. Log into your My Verizon wireless account
  2. Go to My Services
  3. Go to Verizon Safeguards
  4. Go to Spam Controls
  5. Go to Internet Spam Blocking and Call & Message Blocking
  6. Save desired configuration

There are 3 options for Internet Spam Blocking you can select from :

  1. Block all messages from the web.
  2. Block all messages from emails.
  3. Block  up to 15 specific email addresses and/or web domains (i.e. domain.com).

There are 2 options for Call & Message Blocking you can select from:

  1. Block all calls & text messages originated from specific numbers
  2. Block up to 5 specific numbers at one time.
    1. Expires 90 days from the date of your first block.

or

  3. Input your desired alias without the “@txt.att.net” in the alias option

Short Code Spam (4-digits are shown, not a phone number):

  •  Reply “STOP” in the body to block sender from spamming messages to you in the future.

Wireless Number Spam - AT&T does not currently offer a Free solution to wireless number spam. The only way to block wireless number spam currently is by signing up for AT&T’s Smart Limits for Wireless. The service costs $4.99/month per line. Similarly to Verizon’s Usage Controls.

You must purchase the Smart Limits feature before configuring Smart Limit options. Afterward, you may set up Wireless number blocking by following these steps:

  1. Log in to your Wireless Account
  2. Click the myAT&T tab

If mobile spam continues to be a problem, you may contact AT&T’s Customer Service at 1-800-331-0500 for additional help or forward the spam to the short code “SPAM” (7726) to open an investigation. AT&T says, “There is no charge to report mobile spam. Messages forwarded to 7726 do not count toward your data usage or voice package.”

Sprint -

  • They have a very complex system to manage text blocking, see this page.

or

  • Forward spam directly to abuse@messanging.sprintpcs.com or call customer care at *2 (Sprint phones)/ 611 (Nextel phones). More information here.

T-Mobile

  • T-Mobile will ask you to send them the number of the original sender so they can try to identify the identity of the spammer

*Note* Sprint does not have auto-blocking available yet & T-Mobile does not currently offer a blocking from the Internet.
