After recharging the phone bill on WeChat mobile phone, the phone bill was recharged successfully, but I received a short message of package payment. What does packaging mean?

This package and payment are the kind of mobile business hall. I also received it here. I downloaded the next one and believed it. I filled in all the others. 30 yuan, that and the package money were also sent by text message. But I didn't pay in his software either. I charged it in other stores, but I also paid for sending text messages with a package.
