Hi John
Yes, AT&T does offer static IP’s associated with a SIM for “mobile terminate data”
You won’t get this at you local AT&T store. You need to talk with a M2M/IOT
division of AT&T that provides this service. AT&T contacts are regional, so
I can not provide a direct contact. Ours are provisioned through our
corporate account. Look at the i2gold APN definition at this link https://developer.att.com/technical-library/apns/apn-descriptions-and-characteristics
Your best bet may be to reach out to the AT&T small business solutions and
have a local rep contact you. https://www.att.com/smallbusiness/explore/internet.html
Another method to remotely monitor/manage Conduits is our free cloud based
device management solution called deviceHQ. https://www.multitech.com/brands/devicehq
