### Chinese: 免费送手机，是保单尾号比如6666，8888这种特殊保单号段才送的，并且如果中奖短信发出，自己不兑换，也没有人提醒的。
### English: Free mobile phone delivery is available only in special policy number sections such as 6666 and 8888 at the end of the policy. <v>If the winning text message is sent, it will not be exchanged</v>, and there will be no one to remind you.
### Errors: There is a major accuracy/mistranslation error at "If the winning text message is sent, it will not be exchanged" within <v></v>.

### Improved English: Getting mobile phone for free means only policy ending with special numbers such as 6666 and 8888 can get a free phone, and no one will remind you again if the text message is sent to you and you don’t redeem it yourself.
