This afternoon, I received a message from China Unicom that "the tariff change business you applied for has been successfully handled", and also presented 500M provincial traffic for half a year.

Hello, the tariff change refers to the tariff change of mobile phone package. At present, China Unicom gives away 500M traffic to new and old users for 6 months for free. The landlord doesn't have to worry about other charges. There is also a complimentary 500M flow, which is the flow in the province. Pay attention to the use of traffic when you go out.
