Finally! A way to block spam text messages on my AT&T cell phone.

Last time I checked, I could not find a way to block spam text messages through my AT&T account. Today, I received another spam text message, so I decided to look around again, and I was delighted to discover that AT&T now provides a way to selectively block text messages. I have no idea when AT&T started providing this option – I never received any kind of announcement of it and I haven’t seen anyone blogging about it, so I think it is a little known, probably recently released, option.

Now you can login to a Messaging Preferences page and set options to block text messages. You’ll have to register your phone number and a password before you can log in (even if you are already logged into your AT&T account). After you register, AT&T will text message a 5 digit registration number to your cell phone and then you can complete your registration and start changing options.

Your choices are to:

  • Block text messages sent as email (from email accounts)
  • Block all multimedia messages send as email
  • Block all messages sent from mobile numbers
  • Block messages sent from specific email accounts or domains
  • Allow all messages sent from specific email accounts or domains

AT&T also allows you to create a text messaging alias for your wireless number, so in addition to sending text messages to your cellphone number, your friends can also send text messages to an alias. If you use an alias, you can give people your alias instead of your cellphone number. If you create an alias for yourself, you can block any text messages sent to your cellphone number and only receive text messages sent to your alias. Now when I set up an alias for my wireless number and tried to send myself a text message from my cell phone, I received an error message on my cell phone that informed me that the alias was not a legitimate phone number and so the text message could not be sent, so I don’t know how useful having an alias will be.

You can select the screen print below to see a picture of the Blocking Options page where you can select these options.

I’d really like to have some options that allow me to block specific cellphone numbers or to allow specific cellphone numbers, similar to the way I can handle spam on my email account. Oh well! At least this is a step in the right direction!

    This isn’t really a way to block text messages. Its a way to block emails from being sent to your phones email address. You still can get spam texts, and AT&T has had this for years.

    The only thing that I know of is a company called textgard.com. – It’s pretty new – think still in beta, but they have a way to actually block texts and block spam texts from AT&T, Verizon and any other carrier. I downloaded it last week cause I have a 21 year old stalker that will not stop texting me. So I downloaded textgard.com and blocked her texts. Good luck!

    I’m currently being bombarded with txt messages. It started over 5 hours ago, I’ve already received over my monthly limit, they’re still coming in and I have no idea where they’re coming from. I registered for the AT&T messaging preferences and said to block everything, but they’re still coming. It appears that you can’t block mobile to mobile messages, only email to mobile, and the changes could take up to 24 hours to take effect.

    aquariusrick: I think you need to contact AT&T immediately and explain the situation to them. I’ve read of similar experiences, and when contacted about it, AT&T removed the charges from the cell phone bill.

    You might also look into software that you could install to your mobile device that allows you to “blacklist” numbers. If you can identify the specific number that is sending you all these text messages, you can block the number and then the messages will not be delivered and you shouldn’t be charged for the messages. I have not had a problem like the one you describe, so I don’t know how well this software works. Here’s a link to one such pocket pc application you might want to check out:

    Thank you so much for publishing this information.

    Does anyone know what (text) message the blocked parties will receive after you’ve blocked them from texting? The problem is, I have a colleage who texts me constantly. I’ve asked this person politely to stop on more than one occasion. I don’t want to block them from calling, simply texting. So my questions is what message will they receive? I am hoping that there is some automated message that informs them their message was not delivered. …if blocking their text means blocking their number, I will go along with that. Thanks for any information you guys can share.

    Fall 2009 – site works. Was able to apply mobile number control:
    Mobile number control Do Not BlockBlock
    This option blocks messages sent to your mobile at MOBILENUMBER@txt.att.net and MOBILENUMBER@mms.att.net. You can still get messages sent to your alias. If you want to set your alias, go to the Message Options page. If you are signed up for alerts from AT&T or another company, and if you choose “Block” for Mobile Number Control, you should update your email address on the third-party web site to include this new

    I was also looking for that text blocking options.

    Thanks for posting it!

    This is probably a spam itself. They are collecting your phone number so they can sell your number to telemarketers. I am not doing this.

    As your mobile phone provider, AT&T already has your mobile number. They don't need to create a site to phish your number.

    I hate when companies phish for your number and then send you annoying and expensive text. I once had a 8 dollar bill simply from companies that had sent my work phone sms that I had never asked for. Not only did I have to explain to my boss what happened but I also had to pay for the over charges. I did some research and found websites like http://www.smswatchdog.com and whotextsme.com and found that most scammers/spammers stop if you reply stop but thats not always the case…
