How to prevent telecom mobile phone number from being blocked

At present, there are three main reasons for the love of titles. As long as we know the reason and try to avoid it, we can solve it.

One: high-frequency exhalation. Frequent outgoing calls are blocked by big data of the Ministry of Industry and Information Technology. Frequent means more than 30 in an hour, or more than 80 in a day, and so on, it will be regarded as high frequency.

Two: artificial complaints. In case someone complains, the headline is inevitable.

Three: abnormal use. For example, only when the outgoing call does not call, the marked number will be regarded as abnormal and the number will be sealed.

So, avoid complaining and don't be unhappy with each other. In order to avoid high frequency and abnormality, the line is used to switch, and the outgoing call is turned into an incoming call, thus avoiding the trouble of high frequency phone being intercepted.
