我通过answer的代码获得了国家iso：

TelephonyManager tm = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);

String countryCode = tm.getSimCountryIso();

我怎样才能获得国家的前缀电话号码？

例如972 for il.

解决方法:

我找到了一个可以在csv文件中获取映射的地方. check here.

此外,我将其更改为将国家/地区代码转换为电话前缀的类.这里是：

public class Iso2Phone {

public static String getPhone(String code) {

return country2phone.get(code.toUpperCase());

}

public static Map getAll(){

return country2phone;

}

private static Map country2phone = new HashMap();

static {
