Thank you for the reply,
I am using the default APN that comes with Windows 10 I guess. Had no issue working on my Verizon SIM card.
What do you mean by "broadband"?

broadband is the name of the APN that AT&T uses.

Since Windows has a default APN I guess I will have to created one for ATT right?
Not sure what to enter on the empty fields.
Please see my attachment.
Thank you

That should work but it might need to be a lowercase B?

If your using it on a Windows machine, you may also want to try
Skylight Manager to configure the APN.
There was a time we were building PC's with MC7455 to act as media centers and the Skylight Manager worked well for controlling the MC7455 modem.
