Who knows how to cancel Unicom's SMS package service?

First, you can call a worker to see if he can help you. If not, you can go to the business hall with a valid ID card. If your card is not handled with your own ID card, then go directly to the account. But before transferring money, be sure to ask what to do when closing the account, so as not to cause new trouble for using the card in the future. Personal opinion, hope to adopt.
