OnePlus 7TPro service issues

Must mean that 3g shutdown has completed in your area as of yesterday. Unfortunately, the OnePlus 7T Pro [McLaren] is not on the whitelist of acceptable phones and it will not do LTE/VoLTE calls. https://www.att.com/idpassets/images/support/pdf/Devices-Working-on-ATT-Network.pdf

Samsung Galaxy S8 Cannot Make Calls

Yelp you need to get a new phone as yours is no longer compliant with ATT as you need a phone that has VoLTE which yours does not.  None of the U1 8 series work. Here is the list of working unlocked phones. https://www.att.com/es-us/idpassets/images/support/pdf/Service-Capabilities-Unlocked-Devices-ATT-Network.pdf

Phone hangs up after 8 hours of talking

Hello Community, The network is operating correctly when this occurs.  This is not a process that is limited to AT&T, and most wireless providers have similar processes in place.  If your call does not recognize any noise for approximately 3 hours, it may be disconnected.  There are many purposes for that, one of which is to prevent people from accidentally leaving an active call going and tying up resources. Please note, @formerlyknownas is correct, by exceeding the time limits indicated, it would be a violation of your terms of service. Thanks Tim, AT&T Community Specialist
