Please consult with your legal counsel before commencing a messaging program in order to determine the applicability of any legal requirements specific to your situation. Specifically, the TCPA, CTIA guidelines and other applicable laws and regulations that may impose obligations in respect of certain kinds of messaging programs.

What does “Error Code: 5” mean?

If you see “Error code: 5” in the portal, it is most often an indicator that the recipient number cannot receive text messages usually for 1 of 3 reasons: the number is a landline; the number is a mobile under a prepaid service that does not include SMS or MMS; and/or the mobile user has voluntarily blocked text messages.

If you believe you are receiving this error by mistake, you may contact AT&T Landline Texting support for additional assistance at 866-563-4703 on Monday through Friday from 9 am-6 pm EST or Saturday and Sunday from 10 am-7 pm EST. Please be prepared to provide your account number as well as the phone number receiving the error.

Can a customer opt-out of receiving messages from my business?

The end user can opt to stop receiving text messages from your business at any time. To opt-out of receiving text messages:
1. The end user can reply to your message or send a new message to your business phone number with the word “stop”.
2. The end user receives a confirmation message that they have “opted-out” of receiving messages.

If your business sends a text message to a user who has decided to stop receiving messages, then the message appears in the Message Thread but the message is not sent. The text “message failed” appears in red text at the bottom of the Message Box. If the sender moves the pointer over the red text, then a message box appears that describes why the message was not sent.

Is it possible for a customer to opt back in to receiving messages from my business?

For the customer to begin receiving messages again after they have opted-out, the customer sends a text message to your business phone number that includes only the word “start”.

What are Keywords?

Keywords are automated responses triggered by specific words texted inbound by a contact. Utilizing keywords can assist you in more efficiently fielding, directing, and monetizing customer interactions. Set keywords like “hours”, “appointment”, or “directions” will trigger automated responses with the exact information customers are asking for. You can even throw in a link to your website, social media accounts, or advertising partner to give your customers quick access to additional resources.

Keywords are a premium package feature. If you are interested in adding keywords to your account, call the AT&T Landline Texting Customer Service team at 844-947-9447 or contact Advanced Solutions Customer Service team.

 What are the differences between Active and Inactive status for users?

Additionally, Active users contribute to the number of users allowed to that specific package whereas Inactive users do not.

An Inactive status means that the user cannot log into the any of the applications. The user is unable to send or receive messages. The user does not have visibility into the system and does not contribute to the number of users based on the package.
