Tiktok privacy policy says that TikTok can also determine its users' location through sim card info even if the GPS service is turned off. Tiktok 隐私政策称，即使关闭 GPS 服务，TikTok 也可以通过 sim 卡信息确定其用户的位置。 So, I just want to know how it's possible and how they are doing it?所以，我只想知道这是怎么可能的，他们是怎么做到的？ I am writing an app for iPhone which requires users' locations to work properly.我正在为 iPhone 编写一个应用程序，它需要用户的位置才能正常工作。

I'm not an iPhone dev, but the MCC ( Mobile Country Code ) can be returned from the.network operator.我不是 iPhone 开发人员，但可以从网络运营商处返回 MCC（移动国家代码）。 It won't give you a precise location (it's country level), but it doesn't require GPS.它不会给你一个精确的位置（它是国家级别），但它不需要 GPS。

There are a few parameters on Sim Card chip that Tiktok is interested in and based on that I can determine user "home" country. Tiktok 对 Sim Card 芯片上的一些参数感兴趣，我可以根据这些参数确定用户的“原籍国”。 So country that sim card was issued (sim card home.network country).所以 sim 卡发行的国家（sim 卡 home.network 国家）。

Basically MMC + MNC tell Tiktok What country was sim card issued and what is its home.network.基本上 MMC + MNC 告诉 Tiktok sim 卡是哪个国家发行的，它的 home.network 是什么。 Here is he full list: https://tik.cards/mobile-country-code-and-mobile.network-code-list/这是他的完整列表： https://tik.cards/mobile-country-code-and-mobile.network-code-list/

Below is the example of card i use (this one is from Tik.cards ) for Japan.. You see it uses MMC 440 and MNC 10, and its "home" conutry is Japan.下面是我在日本使用的卡片示例（这张来自Tik.cards ）。你看它使用 MMC 440 和 MNC 10，它的“家”国家是日本。 4 4个
