How to limit cellular data usage on your iPhone or iPad

If you have a fast enough cellular data rate (3G or faster), you can watch HBO GO using your cellular connection. However, streaming video uses a large amount of data, so you might want to be careful about when you use your cellular connection.

HBO GO has two settings to help you manage your cellular data usage: 

WiFi Only

To limit video playback to Wi-Fi only, go to Settings > Video Playback and turn on WiFi Only.

When you limit streaming to Wi-Fi connections, you can only play videos when you're connected to the Internet through a high-speed wireless access point. So if you try to play a video when you're not connected to a Wi-Fi network, you'll get a message telling you to connect to a network or change this setting.

Cellular Playback Warning

To get a warning about cellular data usage, go to Settings > Video Playback and turn on Cellular Playback Warning.

Now before playing a video using your cellular connection, you'll get a message warning you about possible charges from your wireless provider.

Note: Some wireless providers and service plans limit video streaming. Contact your wireless provider to confirm your service plan.
