Are there any device size or model restrictions for Eurostar Odyssey?
Not all smartphones will fit in the cardboard headset, but you can still go on a Eurostar Odyssey with just your phone or tablet.
For the best Eurostar Odyssey, dive into the deep with an iPhone 6, Android 5.0 or any newer iPhone or Android device.
If you’re using an iPhone, make sure auto-lock’s off before you start. Go to Settings > Display & Brightness > Auto-Lock > Never.
