O2 TU Go - Television advert
TU Go is currently available for iOS 5 and above, Android 2.3.1 and later, and Windows 7 for PC.
Download the app onto your phone, tablet or PC. You don't have to install it on your phone for it to work. You can download the app as many times as you like, but you can only be logged in on a maximum of five devices at one time.
Tap Sign up to start creating your TU Go account. You'll need signal for this, so make sure you're connected to the O2 mobile network and keep your O2 phone handy. If you have problems during sign up, read our help articles.
Start making calls and sending texts from TU Go on any supported device and watch your Timeline fill up with your communication history.
TU Go is a free app that lets you use your O2 number on tablets and laptops.
It's just like using your phone – you can log in to TU Go to get your calls, texts and voicemail on up to five devices. And the person you're calling doesn't need to have the app.
Calls and texts you make through TU Go cost the same as on your mobile, and come out of your monthly allowance. If you've used up your allowance, we'll charge you the standard rate.
The app also uses a small amount of data to sync your Timeline and voicemail – this will come out of your data allowance.

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're not on wifi and make a call through TU Go, you'll be charged at the normal roaming rate – a pop-up will appear to let you know.
If you leave your data switched on, TU Go's 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.
To avoid charges, switch off your data roaming:
