根据官网的解释
You’ll start the transfer once you have your phone. Here's how long transfers usually take to complete:
84% of transfers: Less than 15 minutes. 84% 只需要少于15分钟
13% of transfers: Between 15 minutes and 24 hours. 13% 在15分钟~24小时之间
3% of transfers: More than 1 day. 3% 大于 1天
Note: Transfers from Google Voice or Republic Wireless can take up to 24 hours.
如果你从Google voice或者 Republic Wireless 转号码，最多24小时 【其实这个有例外的，我就见过花了几天都没转成功去Fi的GV号码】
