Try popping into airplane mode and then back out to reestablish an updated mobile network connection. That's what worked for me. Good luck.This morning, still having some problems. But it begins to seem like the issue may be with the provider servers, as suggested by DBCooper. Drove to Whataburger for breakfast and still could not connect. At home I can connect, but only when I'm using WIFI. When I change my connection to a MOBILE connection, I cannot connect.
