Why does Apple's mobile phone have a charge deduction message from 29 yuan?

For the platform services that are authorized to be bound, the fees are deducted.

According to Apple official website's query, Apple's mobile phone has the charging information of 29 yuan, which may be because the members who bought it before began to renew their fees automatically, and the platform services bound by authorization were charged on the expiration date.

Apple's mobile phone is a mobile phone product released by Apple at the Macworld conference held at the Musconi Convention Center in San Francisco, USA on June 9, 2007.
