删除总得有个确认吧，我冒险打开删除界面看了下，还是有些注意事项的：
– You will no longer be able to receive calls and text messages on this number
– You will still be able to place calls from Gmail or from Hangouts
– All your messages and call history will remain available in your inbox
– After deleting your number, you will not be able to sign up for another number on this account for 90 days (if you just want to change your Google Voice number, click on the “change/port” link instead)
– You will retain the ability to reclaim this number for 90 days, after which it may be reassigned to another user

第四条，删掉后，三个月内不能新选号；第五条，三个月内可以拿回号码，否则有可能给别人……
太冒险了，我还是花个 10 刀稳一波吧，之前接了好几次码，都没有成功，这反正也是个小号，就算过期了也没事，大号干这个还得多花 20 美元保旧的大号。
