Samsung S9+ not working on PureTalk

I got a notification from PureTalk that they are shutting down the 3G network and my phone will stop working. I don’t know why I’m getting this message as the phone connects to and uses the 4G LTE network. As of now I can not make calls over PureTalk, which uses the ATT system.
