With Tu Go, O2 customers have been able to make calls on their laptop or send texts using a tablet for some time now. It's a simple service, but it always required a separate app to get things done. Luckily, that's changing today, after the operator announced that it's brought its multi-device platform to the web. To take advantage of the service, customers need to point their browser to the new Tu Go web beta, which provides options to either sign up or sign in with a mobile number. It's powered by WebRTC, allowing all modern browsers to connect you without the need for additional plugins or software. Right now, the tool supports outgoing calls and the sending and receiving of texts, with the ability to receive calls coming a little later.
