Telefonica's own 'OTT' style messaging service hits Google Play.
The big operator unveiled Tu Me for iOS last month as an that lets users make calls and send messages 'free' without using up their quota of call minutes or texts. Instead, the usage uses data, which is part of the monthly data allowance. Or they can use wi-fi.
Its launch is a further reminder of the radical change in the operator mindset, from one that feared VoIP (and the 'over the top' messaging services like Skype, WhatsApp, BBM and Viber that were driving it) to seeing it as an opportunity to sell more data.
The launch of TU Me on Android makes it available to more than 300m Android users regardless of country or network operator.
Communications are stored in the cloud so if the user loses their device they can restore their timeline when they log back into the app on their new handset.
The app now includes support for Spanish and offers push notifications.
“We said that we’d make TU Me available as quickly as possible on Android and are really pleased that it’s taken just a few weeks,” said Jamie Finn, director of communications products at Telefónica Digital.
“Since we launched on iOS last month the customer response has been phenomenal and we will continue to adapt and evolve the app so we can constantly improve the customer experience.
"TU Me is the first product from Telefónica to launch under the new TU brand. It promises more to come in the next few months.
