What's the difference between directional flow and ordinary flow?

The difference is that directed traffic can only be used on designated apps. Ordinary flow is not limited.

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.

Extended data domestic directional data traffic refers to the data traffic generated when users choose designated access points to use specific services in China through China Unicom. When using other non-specific services, it will consume the traffic included in the package. When the traffic generated by using a specific service exceeds the limit, it will be deducted from the data traffic included in the package. The specific tariff is subject to the package tariff.
