VoIP provider Truphone is offering customers free calls to America for 12 hours on November 26 for Thanksgiving.
Free calls can be made to mobiles and landlines in the country between 12pm to 12am GMT time (7am to 7pm EST) on the day.
Truphone has applications for the Apple iPhone, iPod touch, BlackBerry, Nokia and Android handsets.
Truphone chief executive Geraldine Wilson said: “Thanksgiving is a day when family and friends come together to celebrate and catch up across the U.S.
“For those people who can’t get home for the holidays, often because distance is too much, a telephone call to let them know how they are is the next best thing. With this initiative, we are allowing people who can’t be together to catch up on this special day.”
