Suggestion- if you are planning to go abroad

I have to go to US now very often on business trips. When I go there I need to call home every now and then which adds to my budget. I have recently started using PCO4NRI calling service which has actually helped my balance my budget. This service has several plans for different users but the one that suited me the best was the traveller's plan. Thought this would help all those who travel abroad often.
