Android读取SIM卡ICCID-Toy模板网

这篇具有很好参考价值的文章主要介绍了Android读取SIM卡ICCID。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

方法一，使用TelephonyManager的getSimSerialNumber()获取

TelephonyManager telephonyManager = (TelephonyManager)context.getSystemService(TELEPHONY_SERVICE);
String iccid = telephonyManager.getSimSerialNumber()

需要添加权限：<uses-permission android:name="android.permission.READ_PHONE_STATE" />

方法二，通过发AT命令读取SIM卡ICCID(可以解决读取某些SIM卡ICCID长度不对的问题)文章来源地址https://www.toymoban.com/news/detail-588322.html
