To make a long distance call, you need to dial 011 for international or 1 for North America. 

If you dialed the right number properly and hear “the number you dialed is not invalid”, it means your long distance is locked or it is over limited, if you haven’t paid your invoice, you can make payment online using credit card from my CIK account and it will automatic unlock your long distance. Or you might contact our customer service to enable long distance or increase limit. 

If you dialed the right number and hear fast busy or dead air, you might try different way such as using third party long distance company to test the number if correct or not. If the number has been verified to be correct number, you can report to our customer service to investigate for you.
