Hello, you have check-in traffic every day. Why do you always say that this opening failed?

One case is that Unicom (Mobile) Company is engaged in activities, and the activities have expired. Even if the monitor receives traffic, it is invalid, so it will show that it has failed to open.

On the other hand, after receiving the check-in traffic, prove its authenticity and call 10086 or (100 10) to check the cost of your mobile phone. If there is traffic during the check-in, a text message will come in a few seconds, which contains the details of the expenses you used this month and the usage of traffic. If there is unused traffic or sign-in traffic, the sign-in traffic is real and effective.
