Is there a list of the SMS numbers that AT&T uses to send text messages generated through the “email@example.com” email address?
When I receive these text messages to my phone, they have a number followed by prefix to identify the message. Eg. 1 (210) 100 -063, 1 (210) 100 -064.
I am looking to gather a list of all of the SMS numbers (the 1 (210) 100 portion). I have alerts sent to my phone for one of our software products at work. We can receive a number of alerts throughout the day. It would be easier if I group these numbers under one contact. Since they are received as a new number each time, they appear in my phone as a new message which makes them difficult to manage.
Did the application make this change to mms.att.net? I support an application that is causing the same issue as you mentioned in your initial post. Our customers are complaining they can't set a specific alert due to the changing numbers. Thanks
