Do you have to log into each Boingo hotspot? Do you just auto login once the Boingo app is on your phone? I also have Amex Plat and will have Fi here shortly on a 6P. Just curious how this works. I've never downloaded the Boingo app.
With the app you sign-in once with your boingo login and password. From them on in, it's already set. It's not completely seamless for reasons mentioned before, but it's not terrible.
