Problem With Calling Into Um Number!

[Bossman]

I would say the issue is with the calling card (CC). It initially worked because it's the first time someone is using that calling card to call a FL number. The CC company may have not been charging calls to FL mobiles appropriately and they may have ceased completing calls once they found that out, till they put the appropriate charges in place. The calling card I use here in the states to call FL mobiles completes 40% of the time. Calling directly from any phone completes 100% of the time.
