How to get it

  1. Check your device

    TU Go is currently available for iOS 5 and above, Android 2.3 and later, Windows Phone 8 and above, plus Windows 7 for PC.

  2. Download the app

    Download the app for your smartphone, tablet and PC. It doesn't have to be installed on your phone for it to work. You can download and log in on up to 5 devices at any time.

  3. Create an account

    Tap Register to start creating your TU Go account. You'll need to be able to receive a text to sign up, so make sure you've got signal and keep your phone handy.

    Signing up for TU Go will make some changes to your O2 account - we ensure voicemail is switched on for your phone number (you can switch this off again from the app). All call forwarding or diverts you had will be turned off while your TU Go account is active.

    Is your phone covered on O2 Mobile Insurance? If your phone has been lost, damaged or stolen, you can use TU Go to stay in touch on any other device while you wait for a replacement. You just need to have set up your TU Go account, and have received the confirmation SMS, before the phone is lost.

How TU Go works

TU Go is a free app that lets you use your O2 number on smartphones, tablets and laptops.

It's just like using your phone. Sign in to TU Go using a wifi connection to get your calls, texts and voicemail on up to 10 devices. The person you're talking to doesn't even need to have the app.

Our latest version of TU Go now also lets you use the app over any mobile data (3G / 4G) connection – so you can now use TU Go for calls, texts and voicemails whenever you have mobile data available. If you want to use mobile data for TU Go calls, you can switch this on in Settings.

Cost

Calls and texts you make through TU Go cost the same as on your mobile and come out of your monthly allowance.

The app also uses a small amount of data to sync your Timeline and voicemail - make sure you're connected through wifi, so you're not using your mobile data allowance. If you switch on calls over 3G/4G in TU Go Settings, TU Go calls will use up your monthly allowance of mobile data as well as your allowance for calls and texts.

If you've used up your calls, texts or data allowance, you'll be charged at the standard rates.

Getting TU Go

TU Go is available on:

  • iPhone, iPad and iPod Touch (with iOS5.0 or higher)
  • Android phones and tablets (with Android 2.3 or higher)
  • Windows Phones (with Windows Phone 8.0 or above)
  • PCs (with Windows 7)

Download the app from:

  • Apple's App Store
  • Google Play
  • Windows Phone Store
  • Download TU Go PC version for Windows 7 (see download section above)

Download the app onto your phone, tablet or PC and register with your Pay Monthly number. It doesn't have to be installed on your phone for you to receive calls.

You can download the app as many times as you like, but you can only be logged in on a maximum of 10 devices at one time.

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, people can call you via TU Go by dialling your mobile number as usual.

If you call or text on wifi only, it'll cost the same as if you were in the UK, and come out of your monthly allowance. Calls to international numbers will be charged at the usual UK rate.

If you leave your data switched on, TU Go's Timeline and voicemail will keep syncing over the mobile network and you'll have to pay the roaming charges for using data abroad, which can be very high. If you switch on calls over 3G/4G in Settings, making and receiving TU Go calls may also incur roaming charges.

To avoid charges, switch off your data roaming.
