3G phone still getting data

I have a Samsung Galaxy Note 8 (purchased at the local AT&T store) that I found out is a 3G device. Currently do not have any cell phone service (call or receiving), yet I still have data service. How is this possible? I would think that the data services would use the same service (3G) as the cell phone and data should not be available. I have been in contact with AT&T service multiple times trying to see what I can do about the phone. They told me a) would call back within 24-36 hours after they reviewed the problem (never received a call; b) called them with the ticket number (which they didn't have in their records). This time was advised the phone is a 4G device and to get a new SIM card. At the AT&T store they put in a new SIM card and when the phone powered the error message said the phone is a 3G phone; c) called AT&T service again told them what the AT&T store employee said. They will again review the problem (increased it to a high level priority - RIGHT) and call back soon. That was 24 hours ago and still waiting.

The issue has always been voice calls. Voice calls must work over the LTE network (VoLTE) .  Not all phones are capable of working on AT&T voice over LTE. If your Note 8 is from a different service provider, and not one of the accepted model numbers , your phone reverse to 3g for phone calls. This does not affect data or text messages.

If you did purchase your phone directly from AT&T, and when you start the phone off it boots with an AT&T blue Globe, then it should still work. The problem maybe the IMEI is incorrect, or your sim card is old and not capable of HD voice. Start by having the SIM card replaced at a local AT&T store. At that time they can also correct the IMEI and see if they can get you working again.
