MCC 与 MNC 代码是什么
移动国家码（MCC）和移动网络码（MNC）合在一起，标识一个移动网络。写作 MCC-MNC，或连写成 PLMN 标识，这一对代码就是每个 IMSI 的前五或六位。IMSI 是存在 SIM 或 eSIM 配置上的用户身份。网络会广播这对代码，让设备知道自己接在哪个网络上。
ITU 按 E.212 建议书把 MCC 分配给国家和区域，各国再把 MNC 分配给运营商。有的国家用两位 MNC，有的用三位，少数两者都有。因此 334020 在墨西哥读作 MCC 334、MNC 020，72405 在巴西读作 MCC 724、MNC 05。前导零不能省，02 和 002 是两个不同的代码。
代码比品牌活得久。运营商会为新网络、独立的物联网或测试网络，或通过收购拿到额外的代码。许多运营商还保留着被收购公司的代码。代码也可能被退回，闲置多年。所以一个运营商常出现在多个代码下，代码表里的品牌也可能与分配记录上的公司名称不同。
工程师在几类工作里会遇到 MCC-MNC：读网络和漫游日志，配置引导或漫游列表，按号码所属网络路由短信，或准备 eSIM、多 IMSI 配置。解码 IMSI 前几位可以看出 SIM 的归属网络，但看不出设备当前在哪里，也看不出此刻接在哪个网络。
公开代码表彼此不同，因为每个来源的更新节奏不一样。每条记录上的来源日期和代码本身一样重要。先看状态和日期，拿代码做路由或计费前，再向监管机构或运营商确认。
