If you're in China and use a free chat app called Weixin on Android or iOS, you're about to get no-charge VoIP as well thanks to an imminent update. The company is set to join the likes of Skype, Viber and Korea's Kakao Talk in providing free cellphone calls to the nation and ought to make a huge splash given the massive 100 million user install base. The Tencent-owned service is also adding Bluetooth support, a matching VoIP web service and a complete redesign of its site, according to TechNode. There's no release date yet or word on whether the English version WeChat will get it, but if so, it might make those pricey cellphone calls to friends and family overseas a lot freer.
