Does anyone know why the below might be the case ? AT&T printed this in small print on bills sent to customer in January. Considering that AT&T is the largest telco in the US this is a serious issue : International Call Origination: Effective March 1, 2007, our International Call Origination service will change. Current access numbers for calls originating internationally will change. Please visit att.com/dialing-guide to print the new dialing-guide for your reference; or call the number on your bill to order a new dialing guide. Calls from Kenya to US will no longer be supported. International to international calling from St. Martin will no longer be supported. Also, International service will be expanded to over 60 additional countries.
