Q: Is the 250 a monthly fee or one time only fee?
A: The 250 for account setup is a one time fee. There is also a monthly minimum of 50,000 minutes which at .005/min equals 250. This is a monthly 250 fee for using the prepaid calling card platform and includes technical support.
There will be monthly fees for access numbers depending on where the access numbers are and if you require guaranteed simultaneous channels.
