How does Unicom change 8 yuan package to send short messages?

At present, China Unicom has no way to change the tariff of mobile phone package through SMS. If it is necessary to change the packaging, customers can choose the following methods:

1. Single card customers can choose to use China Unicom APP: select "Service-Handling-Package Change";

2. The owner carries the original personal ID card to the local Unicom's own business hall to change the package.

Tips: The display of self-service function is slightly different due to the different cities of customers, which is subject to the actual page display.
