How to cancel the Unicom free combination package?

Unicom's package cannot be cancelled. If you feel that the free package is not suitable for you, you can choose other 4G packages and enter Unicom's online business hall. After logging in, you can change the 4G national package or 4G campus package by selecting the 4G package. Of course, if the tariff is not suitable, you can also re-select the optional package of the combined package in the 4G combined package or change it to other combined packages.
