回答1:

The URI you want to use is this one : content://icc/adn/

Moreover, you have to use the name and the number to delete a contact.

Try something like this (works for me) :

Uri simUri = Uri.parse("content://icc/adn/");
ContentResolver mContentResolver = this.getContentResolver();
Cursor c = mContentResolver.query(simUri, null, null, null, null);
if (c.moveToFirst())
{
    do
    {
        if (/* your condition here */)
        {
            mContentResolver.delete(
                simUri,
                "tag='" + c.getString(c.getColumnIndex("name")) +
                "' AND " +
                "number='" + c.getString(c.getColumnIndex("number")) + "'"
                , null);
            break;
        }                       
    }
    while (c.moveToNext());
}

Off course, don't forget these permissions :

<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_CONTACTS" />
