I have Verizon LTE, so it should load just fineAre you sure your phone has internet connectivity? This happens to me on my iPhone 4S (which is among the oldest and most unstable platforms Go can be played on) whenever my phone isn't connected to internet, since the device doesn't have data at the moment. Otherwise, you may need to reset the app by double-clicking the home button on your phone and swiping up on the app. These fixes generally help.
