注意：
在使用手机号的正则的时候，需要及时的关注，移动、联通、电信等运营商是否新增加了手机号段。以免手持新增网段的用户在注册的时候，输入正确手机号，怎么也不能注册，导致用户被流失掉的问题发生。
个人在做这一块的时候，突然意识到这个问题，期望各大运营商能够为外界提供一个查询网段的API，这样我们的正则验证就能拿到最新的规则。但是非常的遗憾，我没有发现这样的API，如果有了这个API，其实也不好，该API的持有者，会根据请求的来源知晓你的App有那些用户，从另一个角度来说，对数据的安全也不是很好。想来想去，我们还是即时的关注主流运营商对号段的更新，但是客户端不能做到及时更新，或者说每次更新都要重新去审核，如果安卓端的多渠道打包上传，加在一起时非常的费时间的，综合了一下，还是不要去做手机号合法性的验证，但是简单的验证是必须的。
不知道，看到这里的猿友们，有没有什么更好的见解，请分享给我（直接写在评论里，我就能看到，谢谢）。
