A woman's mobile phone card in Jinan was stopped by the operator for no reason. Is it illegal for operators to do so?

According to news reports, on April 3rd, 200212002, Ms. Liu's telecom number in Jinan was stopped by the operator for no reason when the phone bill was sufficient. According to the reporter, Ms. Liu is usually busy at work. She called 10 for work reasons that day, but she couldn't call again. She thought her phone bill was used up, but after inquiry, her phone bill was still more than 200 yuan. Why was her mobile phone stopped by the operator for no reason?

After the phone was stopped for no reason, Ms. Liu's mobile phone received a short message from the operator, informing Ms. Liu that it had been stopped because of an abnormal call from the mobile phone card. If you need to lift the restriction, please go through the relevant formalities in the business hall. However, Ms. Liu said that the calls she made were all customers or friends she usually contacted, and there was nothing unusual, and the phone bill was sufficient. Why was she stopped for no reason? Ms. Liu said: I will not go through the cancellation procedures, but I will complain to the relevant departments about my experience. After two days of communication and coordination, the operator finally made concessions and lifted the restrictions on Ms. Liu's mobile phone card. At present, Ms. Liu's mobile phone card can be used normally.

1. The standard of abnormal call is obviously too low. Judging from news reports, the so-called call abnormality standard of operators is too low. Ms. Liu only dialed 10 for a period of time, which was judged as "abnormal call" by the operator. This sounds really funny and unconvincing. It is normal for ordinary people to make 30-50 phone calls a day. If you are busy at work that day, there will definitely be more phone calls. However, as soon as Ms. Liu called 10, she was judged to be abnormal by the operator. Is this standard a bit too low?

2. It is inappropriate for the operator to stop without reason. Consumers bought the mobile phone card of the operator, and ensured that the phone bill was sufficient, and consumers had the right to talk freely. Operators shall protect the relevant rights of consumers without violating the rules. However, when the operator unilaterally determined that it was abnormal, it stopped without informing Ms. Liu in advance, which violated Ms. Liu's right to call freedom, which was a breach of contract and obviously an improper practice.

3. Ms. Liu Can kept relevant evidence and took up legal weapons to defend her rights. From what happened above, we can clearly know that it is inappropriate for operators to turn off their phones without authorization. Ms. Liu Can also kept relevant evidence and took up legal weapons to defend her right to freedom of speech.

At present, after coordination by many parties, Ms. Liu's mobile phone has been lifted by the operator and can be used normally. How to treat this practice of operators?
