询问用户的SIM卡PIN
问题描述：
我搜索了一个问题，与此类似，但没有运气。
I searched for a question similar to this one, but no luck.
我正在写一个应用程序，以便正确地验证用户的身份，就应该要求他输入正确的SIM卡。有没有可能，否则我将不得不用户PIN另一只为应用程序的认证？
I'm writing an app which, in order to correctly authenticate the user, it should ask him to input the correct SIM Card. Is it possible, or will I have to user another PIN just for the app authentication?
答
我不知道这是否是可能的，但也有一些没有SIM卡在那里的设备（个人认为只有WLAN片），它可能是一个更好的想法有一个不同的PIN未被SIM卡相关
I am not sure if it is possible, but as there are devices out there that have no SIM (think tablets with WLAN only), it may be a better idea to have a different PIN that is not SIM-related.
