How does Tianjin mobile integral exchange preferential traffic service?

There is really nothing that can be converted into preferential traffic service, but you can convert it into telephone charges first, and then open a mobile data traffic package. Call charges can be exchanged by SMS: 100 yuan, just send DH37 to 10086002 1, 3000 points. DH36 sends the call charge of 50 yuan to 10086002 1, and the integral 1500.
