AT&T notification msgs

[DianeS]

Using AT&T as the service provider, texts are sent to assignees as 1 (410) 000-001, then the next message is 1 (410) 000-002 etc. Assignees want to set a specific alert for that but is unable to do so because it is constantly changing to a different last digit.   Looking at the AT&T forum website it stated to use @mms.att.net     instead of       @txt.att.net

Setting up a 'Notification Service Providers' record using mms.att.net as the SMS Provider Email Suffix does not work.   The email is sent from SN (in our email log) but the subscriber never receives the text on their AT&T cell phone.

Any thoughts or ideas on how to fix this?   This is not a problem with other carriers.   Our company is pushing to eliminate pagers but customers are reluctant because they can't set up specific alerts for SN messages.

Thanks

Diane,

I just tested with a coworkers AT&T phone and it worked without issues.

Here are the headers from the message that was sent:

Date: Thu, 10 Dec 2015 13:51:26 -0800 (PST)
From: IT Service Desk <**********@servicenow.com>
Reply-To: IT Service Desk <**********@servicenow.com>
To: 1112223333@mms.att.net
Message-ID: <22731552.8.1449784286963.JavaMail.p16053@app128067.sjc5.service-now.com>
Subject:
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Can you confirm that the To: header is formated properly as ##########@mms.att.net?   Have you tried other users phone numbers?

Thanks

Brian

It worked!!! We had been setting the device as a SMS vs an email device.

AND we had to totally delete all cell phone device setups in our profile (the txt… ones also).

Now the other system guys with different cell phone providers are playing with their setups also ☺

Thanks for all of your help, it was very much appreciated.

Hello - I am having the same problems, and had a question.......in reference to your comment " ....had to delete all cell phone device setups in our profile....." Did you have to go through all of your devices that were set up to AT&T and remove them?   If not, how was this accomplished?     Don't want to break anything for our AT&T users.  

Thanks,

Clark
