UK MOBILE NETWORK O2 rolled out its own voice over IP (VoIP) service today that allows customers to make calls over WiFi on a number of supported devices using a dedicated app.
Working in a way similar to Skype, O2's Tu Go lets its pay monthly customers make and receive calls over the internet from Apple and Android devices, so you can make and receive calls whether you have a network signal or not. More notably, however, the service works under Windows 7 on PCs, so you can access voicemail messages and send texts away from your mobile handset.
Unlike Skype, Tu Go is not a paid service, so O2 customers don't need a separate account to make calls and receive messages.
"Tu Go integrates seamlessly with the O2 network, meaning customers using the app will experience the same service on, for instance, their tablet, as they do on their mobile phone with any calls or texts sent through Tu Go landing on the recipients' phones as normal," O2 said.
"When a user receives a call, their Tu Go app will ring across all the devices it is installed on, a text message will show just the same as it would on a laptop as it would on their phone."
Users are also able to access their device's local address books and see all their conversations and call history in one timeline on the app, which is also synced across all devices.
The Tu Go app is available now on iPhone, iPad and iPod Touch running iOS 5 and above, Android devices running Android 2.3.1 Gingerbread and above, as well as PCs running Windows 7. It also works on both smartphones and 3G and WiFi supported tablets so customers can choose whether to use it via a WiFi or GSM connection.
O2 claims the development of Tu Go app was to "meet the existing demands" of its customers. It will be interesting to see if its competitors follow suit. µ
