The new app allows users to be logged into the service on five devices at once.
UK mobile phones and broadband provider, O2, has launched a new TU Go Voice over Internet Protocol (VoIP) app to take on Skype. The app allows users to make and receive phone calls, texts and voicemail through a tablet, computer or smartphone.
The new app is being offered on Apple devices, Android devices and PCs powered by Windows 7 operating system, while it is only limited to 'pay monthly' subscribers.
The application deducts charges from the user's existing call minutes allowance.
O2 UK Marketing and Consumer director ,Sally Cowdry, said that customers can now take their mobile number wherever they like, even away from their mobile.
"TU Go lets you take a call on a tablet, pick up text messages on a PC and have conversations in places with Wi-Fi coverage but no mobile signal. We're letting nothing stand between our customers and their number," Cowdry said.
Incorporating Voice over IP and the O2 mobile network, the new TU Go allows users to access their communication history on several devices and can be used through a Wi-Fi or GSM connection.
O2 originally launched the app through Apple's iOS store since October 2012, but only offered it to 1,000 users on a trial basis.
"For the first time, TU Go will mean customers can use their O2 number across a huge range of different devices. It will extend the O2 phone number and package far beyond just the mobile handset," Cowdry added.
"Just as consumers' demands of what their handset can do - and what they use it for - have changed, so we think their demands of their network will change."
