Definition of directional traffic: directional traffic refers to traffic packets used to specify products. Simply put, when using directional traffic (don't exceed the limit), the traffic used will not be deducted from the traffic package you pay yourself.
Generally, directional traffic has usage conditions: some of these "directional traffic" are 500MB, others are 1GB, 2GB, but these traffic have usage restrictions. Some traffic, such as 500MB a month, can only be used locally (some restrict domestic use) and can only be used for 4G services. If you use Unicom's 3G service, you won't use it unless you upgrade to 4G service.
Extended data:
There are many kinds of directional flow:
The "targeted traffic" launched by different operators is different at different times, such as the 4GB local targeted traffic donated by mobile, of which 2GB is video, 1gb is mobile MM, and 1gb is migu music.
That is, you can use 2GB for free when playing mobile "and video". If you play something else, you can deduct the traffic from the package normally, and if you play "and video" for more than 2GB, you should also deduct it from the package. In addition, although mobile gives you free traffic, most of the content is charged. For example, download a song with "migu music", 2-3 yuan.
At the same time, local operators will jointly launch targeted traffic delivery activities with Weibo and WeChat, that is, Weibo and WeChat will swipe their cards locally, and the traffic will not be deducted from the package, while Weibo and WeChat will pay the bill.
