If the function of the mobile phone itself is not charged, if it is through the operator's platform, it is generally charged. In view of the differences in business rules and tariffs among provinces, it is suggested that you can call local 10086 for consultation. Personally, I think there is a mobile business hall operator charge on the mobile phone. Of course, there is a charge. If you enter his door and ask him to do things for you, why don't you charge? Otherwise, what will they use to start a company, open a shop and eat?

Follow the prompts. If you don't charge me, it's free. Otherwise, you will complain if you accept it, and you will be refunded if you accept it. The mobile phone business hall on this mobile phone is also very convenient to handle business. It is much more convenient than the people in this hall.
