Android不支持多SIM卡，从SDK最少。谁创造多SIM设备设备制造商对自己这样做。欢迎您咨询您的设备制造商，看看他们是否有一个SDK插件或东西，可以让你进入第二个SIM卡。

Android does not support multiple SIMs, at least from the SDK. Device manufacturers who have created multi-SIM devices are doing so on their own. You are welcome to contact your device manufacturer and see if they have an SDK add-on or something that allows you to access the second SIM.
