推荐答案

您使用的方法是SDK唯一执行此操作的部分，并且仅适用于将号码存储在SIM卡上的设备上，只有一些承运人这样做.

The method you are using is the only one part of the SDK to do this, and only works on devices where the number is stored on the SIM card, which only some carriers do.

对于所有其他运营商，您将不得不要求用户手动输入电话号码，因为该号码根本没有存储在设备上您可以从中检索到的任何地方.

For all other carriers, you will have to ask the user to enter the phone number manually, as the number is simply not stored anywhere on the device from where you can retrieve it.
