Mobile phone traffic monitoring software shows more than 30 megabytes of traffic, but Unicom's SMS prompt has used 30 megabytes. Why? The manual service can't get through.

The residual flow is greater than 30 m. He said something else.

For example, your monthly total flow is ***40M. If you set the software there for one month, you can use 70M.

Then there are only 30 meters left.

Unicom texted that you used 38M. These two things are different.

The software can be set. But not necessarily accurate.
