How TU Go works

TU Go is a free app for Pay Monthly and Business customers. It lets you use your O2 number on all your devices, including smartphones, tablets, smart watches and laptops.

It's as easy as using your phone. Sign in to TU Go using a wifi connection to get your calls, texts and voicemail on up to ten devices. The person you're talking to doesn't need the app.

Our latest version of TU Go also lets you use the app on a mobile data (3G/4G) connection. If you want to use mobile data for TU Go for calls, texts or voicemails you can switch this on in TU Go Settings.

TU Go also supports video calling and group messaging. To use video calling, start a voice call from TU Go. Once the call starts, an icon for video will appear. Tap this to upgrade the call to video. To start a group message, simply tap the group icon to add contacts. Non-TU Go contacts will receive a text invite with a link to join the conversation.

Getting TU Go

  • Windows Phones (with Windows Phone 8.0 or above)
  • PCs (with Windows 7,8 and 8.1)

  • Windows Phone Store
  • Download TU Go PC version for Windows 7,8 and 8.1 (see How to get it section above)
  • TU Go for Web - Available on desktop web browsers using the latest versions of Chrome, Firefox and Opera

Download the app and register with your Pay Monthly number. You can download the app as many times as you like, but you can only use TU Go on up to ten devices.

Cost

TU Go calls and texts cost the same as usual and come out of your monthly allowance. Sending images and other media costs no more than a text and also come out of your monthly allowance.

Group messages are free, with just an initial text to non-TU Go users to invite them to the group. This initial text will come out of your allowance. Video calling is charged as a normal voice call, and will come out of your allowance.

The app also uses a small amount of data to sync your timeline and voicemail, so use wifi where you can. If you switch on calls over mobile data in TU Go Settings, TU Go calls will use your monthly allowance of mobile data as well as your allowance for calls and texts.

If you've used up any of your allowances, you'll be charged at the standard rates.

Notifications

If you're signed in to TU Go on a smartphone, you'll get a text notification from your phone and another one from TU Go. You can change this in the app settings - just switch Text notifications 'off' and you'll stop getting TU Go notifications for new texts.

Once you've signed up, you'll also get notifications in TU Go for any voicemails that you receive. You can turn voicemail off entirely (for TU Go and your mobile) from TU Go's settings.

Using TU Go abroad

When you're abroad, you can receive calls via TU Go. People can call your mobile number as usual.

If you call or text over wifi, it will come out of your monthly allowance and cost the same as in the UK. Calls to international numbers will be charged at the usual UK rate, including calls to the country you are in. For example, calls you make whilst in Spain to a Spanish number will be charged as an international call from the UK to Spain.

If you leave your data switched on, TU Go's timeline and voicemail will sync over the mobile network. You'll have to pay roaming charges for using data abroad, which can be very high. If you switch on calls over mobile data in TU Go Settings, making and receiving TU Go calls may also incur roaming charges.

To avoid data charges, switch off your data roaming.
