BEWARE!!!! Phonecards-Prepaid.com sells these cards and they just, patently DO NOT WORK, at LEAST 80% of the time. Weekends, forget it. Your chances of getting into the 866 code are approximately like winning the lottery.
When I made a complaint with the seller, Ken Drew, he replied that "there are limited phone lines and THATS why you're getting such a good rate".
Well fine, but a good rate isnt worth spit if you cant get the toll free 866 number.
If you dial the alternate toll free #, it just thangs up on you.
These cards are WORTHLESS & the seller WILL NOT help you, except to email you that HE got thru (he must have called at 4:00 am, the only time I was EVER able to make a call) BEWARE!!!!!!!!!!!!
