5G Service, Nokia XR20
I recently purchased a Nokia XR20, independent of AT&T. The phone is great. No issues. It is 5G capable but I am not sure if it is connecting to the 5G service in my local area. I turned on the 5G preference in the options. (I checked the map and I there is 5G in my area. ZIP Code 22314.) I reviewed the APN and the only difference is the MMC. It is currently set to 280 and everything I see indicates that it should be set to 410. Is there anything else that I need to do? A call to Customer Service for a specific change to my account?
