O2 TU Go - Television advert
TU Go is currently available for iOS 5 and above, Android 2.3 and later and Windows 7 for PC.
Just go to the app store to download, or click the link on this page for the Windows PC app.
Download the app onto your phone, tablet or PC. 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 5 devices at one time.
Tap Sign up/I'm new 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. And you'll also see a TU Go Bolt On in My O2.
With the TU Go app, your O2 Pay Monthly mobile number works on more than just your phone – you can use it on tablets and laptops too. It connects over wifi and you can log in on up to 5 devices at once. Call and text anyone as normal - they don’t need to have the app.
Calls and texts that go through the TU Go app come out of your monthly allowance.
The app also uses a small amount of data to sync your Timeline and voicemails – make sure you’re connected to wifi so you won’t be using your mobile data allowance.
Used up all of your calls, texts or data? You’ll be charged at the standard rates.

If you're signed in to TU Go on your O2 mobile, you'll get a text notification from your phone and another one from TU Go. You can change this in the app’s settings - just switch Notifications off and you won’t get them for new texts in TU Go.
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.
You can use TU Go when you’re abroad. If you connect to wifi calls and texts will cost the same as if you were in the UK, and will still come out of your monthly allowance. Calls made to international numbers will be charged at your usual rate. And people back home can call you via TU Go by dialling your mobile number as usual.
If you're not on wifi and try to make a call through TU Go on your phone, a pop-up will appear, allowing you to switch to your phone as normal. This means you will incur roaming charges.
If you leave your mobile data switched on and you're not connected to wifi, 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 - to avoid any data roaming charges, switch off your mobile data from your device settings.
