Usually a qualified Unicom number, single card, no contract or other preferential binding, you can change the package. I suggest you try to handle it through the self-service channel first.

For example, 2G and 3G upgrade 4G packages. eligible 2G and 3G users can log in to Unicom's online business hall/homepage, click business processing > upgrade 4G > upgrade 4G packages, select the required 4g packages and package contents, and click change. The change package will take effect on June 1 day.

Reminder: From 0: 00 on the last day of each month to 8: 00 on the following month 1 day, old users of 2G and 3G cannot switch to 4G packages for the time being. After successfully switching to the 4G package, they need to restart the mobile terminal to use the Internet function normally.

If you can't handle the above operations, it is recommended to contact Unicom customer service with the number to understand the specific situation.

If this is not the case, it is recommended to contact the Unicom customer service to which the number belongs.
