To avoid unintentional IDD charge while downloading a file from any website, please remember the following:

• Read carefully the instructions as well as the terms and conditions. Should you find words like "you need long distance phone service"' "click the 'Dial' button", "fill in the prefix/access code for your country", etc., then all of these commands suggest that you may need to pay IDD charge to access the website.
• Most IDD charges have occurred while downloading files from pornographic websites. CTM provides a filtering service at no extra cost to minimize the chance from accessing these websites accidentally.
• Use IDD barring facility to avoid making any unauthorised outgoing long distance calls.
