Note: micro-credit real-time dialogue is required for traffic costs, so you try to use the WiFi network, because the small series test this call by flow is more expensive than the phone.
1, under the mobile phone we open the micro-letter, to find real-time dialogue with friends into the chat
2, then there is a + number next to the expression below, we click on it
3, click the real-time walkie-talkie
4, now we have to hold down the middle of the big button, so do not let
