"it is very good call and long ,munities and so on I love so much keeping call"

"Generally, the service is ok.i wish it would have been a little more cheaper. I found another call card that gives me more minutes.still patronizing both anyway.the app should be upgraded so one can add minutes through the app without having to logon through homepage."

"I am very happy with keep calling"

"I do like it. Excellent system and easy to access! "

"I had been totally satisfied until my last purchase of minutes. I noticed you offer the ability for one to put minutes into another person's account. That's what I did, I wanted to surprise my nephew. Turns out he has a plan with his local co (Movistar) so that monies I put into his account were lost since he has unlimited minutes. No one seems to be able to straighten this out"

"Fastest and best calling service"

"Great service, keep it up!"

"So far no problem except for the really long delay when using the toll free number."

"Great Service who which I have recommended to many friends and family!"
