O2 TU Go


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

Good to a point

Okay so maybe O2 should start reading these reviews and do something about this app. If you use SMS then the message string is replicated on TuGo in order. However, that doesn't apply when using TuGo. Sent messages don't appear in SMS so it all gets out of synch. Incoming calls, if you manage to actually connect at all, are interspersed by buzzes that increase in frequency the longer in the call (I have a 50mb fibre connection) until the call just drops out. VOIP ain't exactly new. It should work. No message sound at all. Not even configurable.
It has lots of potential if O2 read these issues and actually do something about them.
Better than nothing at all. Even better if O2 made signal booster boxes for the consumer market. Oh, and fixed mast issues faster.

Works well, very nearly perfect.

Allows making and receiving phone calls with good sound quality from ipad mini. Text messaging works reliably too.
On iPhones native messaging app I can see all elements of a conversation whether the message was sent via text or iMessage, not on Tu though, just the text messages. Minor niggle but need to remember some parts myself and conversations can look a bit disjointed.
For its design purpose, letting you text and call via WiFi when you have no phone signal, it's very useful indeed.


Doesn't work, even when app is open on the phone. I rang my mobile from my landline to test this. No mobile signal, app enabled, connected to wifi and open. No ring, no notification of call, no missed call, no other notification and no voicemail, despite leaving one. On the rare occasions it realised a call is coming in, it rings twice, not long enough to pick up the phone, swipe left, select answer and then connect the call. Usually if a call happens at all the only clue you have is a missed call notification. It also doubles up all texts and notifications. There's no bulk delete, so you have to do this an item at a time. For a free app it's overpriced.
