Movistar has launched its over-the-top (OTT) multi-screen TU Go app in Peru, allowing subscribers to use their Movistar number to send text messages and make calls over Wi-Fi networks via tablets, laptops, notebooks, PCs and smartphones. TU Go is available for post-paid and business customers and uses the minutes and texts from the subscriber’s package, allowing them to continue communicating after their phone runs out of battery, or they move out of signal coverage. The app is available for devices using the following operating systems: iOS, Android, Windows Phone, and Windows 7 or above.
