import android.content.Context;

TelephonyManager telManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
 
// 手機號碼
String lineNumber = telManager.getLine1Number();
 
// 手機 IMEI
String imei = telManager.getDeviceId();
 
// 手機 IMSI
String imsi = telManager.getSubscriberId();
 
// 手機漫遊狀態
String roamingStatus = telManager.isNetworkRoaming() ? "漫遊中" : "非漫遊";
 
// 電信網路國別
String country = telManager.getNetworkCountryIso();
 
// 電信公司代號
String operator = telManager.getNetworkOperator();
 
// 電信公司名稱
String operatorName = telManager.getNetworkOperatorName();
 
// 行動網路類型
String[] networkTypeArray = {"UNKNOWN", "GPRS", "EDGE", "UMTS", "CDMA", "EVDO 0", "EVDO A", "1xRTT", "HSDPA", "HSUPA", "HSPA"};
String networkType = networkTypeArray[telManager.getNetworkType()];
 
// 行動通訊類型
String[] phoneTypeArray = {"NONE", "GSM", "CDMA"};
String phoneType = phoneTypeArray[telManager.getPhoneType()];
