Is it true that mobile reply SMS sends traffic?

It's true. Official website of China Mobile Communications Group Co., Ltd. shows that in response to the call of the country to speed up and reduce fees, China Mobile Group responded with SMS traffic as a special customer feedback activity, without any conditions, which is true. Users only need to edit 20 19 and send it to 10086, and they can receive a reply message, including the age of the network, the specific traffic and the given usage time.
