Describe the bug Can't login in site in Ukraine

To Reproduce Steps to reproduce the behavior:

1. Go to login via GitHub
2. Further login with mobile phone
3. Have that error:

   I'm also try to use more standard number my Ukrainian phone number

Expected behavior I can login in site in Ukraine. In general, why I need phone number if I was authorized via GitHub? In general, other countries do not need such a Chinese authorization system through a mobile phone and so on

由于中国的相关法律法规，我们必须验证账号实名信息。通过手机号进行实名验证是相对方便快捷的方法。

出现这个错误是因为我们目前没有购买相海外发送短信的服务。

我们计划在本周内支持绑定海外手机号，不便之处敬请谅解。

The following is the machine translation

Due to the relevant laws and regulations in China, we must verify the real-name information of the account. Real-name verification through a mobile phone number is a relatively convenient and fast method.

This error occurs because we do not currently have a service to send SMS messages overseas.

We plan to support binding of overseas mobile phone numbers within this week, please forgive me for any inconvenience.

我们已经支持部分海外手机号码注册（包括乌克兰），但是我们无法进行完整测试以确保列表中的每个选项都工作正常。如果在注册的过程中遇到任何问题，欢迎打开issue。

We already support some overseas mobile number registrations (including Ukraine), but we can't do a full test to make sure every option on the list is working correctly. If you encounter any problems during the registration process, you are welcome to open an issue
