absolutely the best service I have ever had as far as phone cards go the calls are easy to make are nice and clear and very reasonably priced I hope you continue with this service Thanks so much Tony Stankovich

Keep Calling is a true bargain and provides wonderful phone service. Because of them, I'm able to talk with my family on a daily basis. The service is very reliable and the voice quality is excellent. Its also very very easy to use. I'll never switch.

Switch from competitor was flawless, service has always been available, quality of voice excellent with rare instances of metallic or weird sound, typical of the technology. I love the ability to dynamically change the destination phone number for the virtual number.
