OBA for iOS won't work on cellular data

For OneBusAway for iOS to be able to work using cellular data, it needs to have permission from your iPhone. (As a security measure, apps themselves can’t set this; you need to give them permission.) If OneBusAway is only working on Wi-Fi, but not with cellular data, here’s how to fix this.

1. Open Settings from your phone’s home screen.
2. Scroll down to the OneBusAway app entry and tap on it.
3. Turn the Cellular Data switch to the ‘on’ position.
