Open iTunes to buy and download apps.


*Currently TU Go is available for Movistar customers in Argentina, Peru, Colombia and Mexico, O2 customers in the United Kingdom, and Vivo customers in Brazil. We will be launching in more countries soon! For more information, please check out*

Text. Call. Check your voicemail. All without a bar of signal. As long as you’ve got Wi-Fi, TU Go keeps you connected. TU Go is available for O2 UK Business and Pay Monthly customers.

To answer calls from the locked screen on iPhone, swipe left when the notification appears and press “Answer”.

TU Go lets you use your O2 minutes and texts over Wi-Fi, on up to ten devices. So next time your phone runs out of battery, you can’t find signal or you’re soaking up the sun abroad, don’t panic. You can still use the minutes and texts from your O2 Bundle.

Who can use TU Go?
- O2 UK Pay Monthly customers
- O2 UK Business customers (excluding Mobex, some B4B and data only tariffs)
- Movistar customers in Argentina, Peru, Colombia and Mexico
- Vivo customers in Brazil

The best bits:

• Stay in touch – choose between your mobile network, Wi-Fi or 3G/4G. And keep connected, wherever you are.

• Travel friendly – use TU Go over Wi-Fi abroad and your minutes and texts will cost the same as they do in the UK.

Here’s what some of our customers have to say about TU Go:

“Thank you O2! The ability to call and text people while I'm on the London Underground with no signal is epic and has had a few people asking me questions on how it works!” – Imhama

“I am currently traveling in South America so this app is saving me large amounts of money... Thanks O2 you are allowing me to keep in touch when I normally couldn't have afforded it…” – Rob Ericsson

“I thought this sounded too good to be true, but it isn't! It does exactly what I want it to. In Wi-Fi only areas, I can make & receive calls, also texts. It works on my iPad as well! Which is more than could be said of WhatsApp!” – Chris_G_Devizes

You can get TU Go on iPhone, iPad and iPod Touch on iOS 7 and above.

Customer Reviews

This app has saved me!!!

My phone went to be fixed (broken screen) and prior to that I came across this app and started using it - how fantastic to have an extra mobile!!!!! Basically all my calls and texts would come through to the app & I even found out that my phone wasn't picking up all my calls but the app was - so when it went to be fixed I asked them to fix this also. It has however been a month and I still don't have my phone back - thank you 02 for this app as without it I'd be phoneless!!! I am a little restricted as my ipad is wifi only - definitely thinking of changing this at some point when the time comes to replace!!
Fantastic app it truly has saved me!!

Good app with some issues

This app is very useful when you have data but no phone signal. I use it as such when in parts of the UK such as the Lake District whereby wifi can be available but no signal due to lack of masts or similar issues.

It's also very useful for dialling numbers not including in your contract, such as 0845 numbers used by many local authorities and big businesses.

The drawbacks with it are that it can be buggy and inconsistent. It's also not clear about it's settings and needs to only operate when I choose or when I have no phone signal. It's quite irritating to get messages and voicemails on this and via my phone capability. I'm experimenting with settings but this app could benefit from clearer instructions and setup.

Buggy and unfit for purpose.

O2 - this app is a disgrace. Contact, call history and SMS syncing is patchy and often incomplete. This app intermittently makes the native iOS calling app malfunction and sometimes makes calls impossible to answer. It was a great solution a few years ago but it's nearly fit for purpose now and with the adverse way it interacts with native iOS features, I don't think it should even be allowed on the App Store. The most ridiculous thing about this is that O2 believe this to be superior to apples own native iOS wifi calling feature which is seamlessly integrated into the iPhones os. O2 block this feature on your new iPhone beachside they believe the ageing and buggy tugo is a better solution. It's clearly not. Please stop being so deluded and stop locking features on the iPhone that we've paid for.
