The Three app is a free utility and tool application available on the Android platform. It is developed by Three, a leading mobile network operator. With the Three app, you can easily manage your account, check your balance and allowances, view your bills, and find support.

The app allows you to view your allowances and current usage at a glance, making it easy to stay in control of your usage. You can also get a breakdown of your bills, including any extra charges you’ve incurred, and see up to 12 months of your previous bills. Finding support is easy too, whether you need help moving your number to Three, changing your payment date, or any other query.

The Three app also offers exclusive access to offers and rewards, and you can connect with Three using Live Chat. You can view your Pay As You Go credit balance so you can plan your next top-up within the app. The app also lets you check when you’re eligible for an upgrade.

Please note that to view your up-to-date account information using the Three app, you’ll need to use Three's mobile network and not Wi-Fi. The app also offers access to Three Communities, a great way to get help, and Three+, which offers rewards. The app is easy to use, with frequently used features accessible through a side menu.
