How to cancel automatic renewal?

If it's the national smooth month of 36 yuan Unicom, you can edit the short message TDCS36 and send it to 100 10 to unsubscribe, which will take effect the next month.

Different types of value-added services have different ways to unsubscribe. You can try to log in to the APP client of China Unicom with your mobile phone number, and then click Services > Handling > Handling Other Services > Handling Value-added Services > Unsubscribe Services, and select the corresponding value-added services to unsubscribe. If cancellation cannot be made through the above channels, it is recommended that you contact the local Unicom customer service for handling.

If you are a member who uses the phone bill and other services, you can use your mobile phone to edit the SMS customer service phone sent to the operator by 0000, and then you can generally cancel according to the SMS prompt.
