Between 2004 to 2005, Vonage launched VoIP service in Canada, Puerto Rico, United Kingdom and other European countries. Vonage phone service charges a monthly service fee, and calls (local, long distance or international) are technical free or unlimited. With more than one million subscribers this year, Vonage continues to offer new services and plans to meet the needs of both business and residential markets.
