What does China Unicom credit limit mean? How to activate it?

The credit limit refers to the maximum amount that your phone bill can be overdrafted for consumption. If the overdraft consumption reaches the credit limit, the phone will be shut down; the phone bill for overdraft consumption can be paid in time according to regulations.

China Unicom will conduct a credit evaluation based on factors such as your historical payment credit, online time and consumption situation, and make appropriate adjustments. If you need it, you can also bring your valid ID card to the local business office for processing.
