工作原理与局限
在您的浏览器中运行：您输入的内容只留在本机，不会上传。
每种标识符都按公布的结构校验：ICCID 和 IMEI 查 Luhn 校验位，EID 查 mod-97，IMSI 查国家码和网络码，LPA 激活码查各字段。工具包还能把激活码画成二维码。
结构校验只说明标识符格式正确，不说明它是否已激活，也不说明由谁签发。全部在浏览器中运行，标识符不会上传。

SIM 与设备的标识符
物联网和 eSIM 项目会用到四种标识符。ICCID 给 SIM 卡或 eSIM 配置编号，IMSI 标识网络上的订阅，EID 标识 eUICC 芯片，IMEI 标识设备本身。它们结构固定，其中三种以校验位结尾，可以抓出输入和扫描错误。
ICCID 通常为 19 或 20 位。开头是 89，即电信行业标识。后面依次是签发方的国家呼叫代码、签发方和账户数字，最后一位是 Luhn 校验位。各签发方写国家部分的方式并不统一，所以它只能当线索，不能当事实。
IMSI 最多 15 位：三位移动国家码（MCC），两位或三位的移动网络码（MNC，取决于国家），再加用户号码。网络码长度不固定，单独一个 IMSI 可以有两种读法，MCC-MNC 表能判断哪种正确。IMSI 显示订阅来自哪里，多 IMSI SIM 正是靠它在不同网络身份之间切换。
EID 是 32 位。89 之后是国家代码、签发方标识、签发方专用信息和个人编号，最后两位是校验位，算法与 IBAN 类似：整个号码除以 97，余数为 1。IMEI 是 15 位：八位型号分配码（TAC）标识设备型号，加序列号和 Luhn 校验位。IMEISV 变体用两位软件版本代替校验位。
LPA 激活码通常以二维码形式出现，告诉设备从哪里下载 eSIM 配置。码里有格式编号、提供商 SM-DP+ 服务器地址和匹配 ID，还可以带服务器标识和“需要确认码”标志。校验位和结构检查能在标识符进入系统前发现错误，减少激活失败和支持工单。
