Telefonica has announced that its multi-device calling and messaging app TU Go is now available in Argentina on the Movistar network. The app enables Telefonica customers to make and receive calls, texts and voicemails on up to five devices using cellular or Wi-Fi networks, with calls and texts taken from existing pay monthly tariffs and bundles. Argentina is the second market for TU Go and builds upon the successful UK launch of the service in February 2013, where almost half a million O2 customers have downloaded the app to date. ‘Mobile traffic is increasing at an unstoppable pace, sparking the creation of new innovative services that are disrupting the way in which we communicate. TU Go is the perfect example of an application that reflects this changing landscape. It enables people to communicate in exactly the way they want to – breaking down the borders to seamless calls and messages on any device at no extra cost,’ commented Ian Small CEO Communications Services at Telefonica, adding: ‘TU Go’s expansion into Argentina highlights the tremendous success of the service in the UK and proves that Telefonica is more than ready to not just compete, but lead, in this fast-moving connected world as we continue our mission to become a digital telco.’ Telefonica is planning further commercial launches in two or three other markets during 2015.
