 I turned off wifi and then everything worked.
 Long ago I set the phone so that if there were wifi, it would use use
wifi instead of costly data.  Who wouldn't want that?  Doesn't everyone
use that?
 But I assumed if there were no good wifi, it would switch back to data.
is that unreasonable?
 What's going on here?
 In the windowshade, for wifi it said Xfinity, but i'm not eligible for
that and even if I were, I hadn't put in the password.  Is the phone so
stupid that it counts that as having wifi?

Wi-Fi is a mess. It's possible to have Wi-Fi such as BT Internet Smart Hub 2 in your home that some devices like for instance Samsung mobile phones of a certain age, just will not stay properly connected to. Connectivity can fail without the Wi-Fi radio indicating that it has lost the connection until quite some time has passed.
