I would recommend using Skype from your computer to either a computer or a phone. The voice quality is better than a phone and the rates are very good - especially for people outside of the US calling a phone in the US. Calls from computer to computer are also free. You can even get a SkypeIn number so people can call your computer as if it were a phone line.

I do not work for Skype but here is the URL:

http://www.skype.com

My experiences with calling cards have not been good - either the quality has been pretty bad or the minutes seem to disappear.

I use 10-10-987
www.1010987.com.

it is e.g. 3 ct per minute to europe
plus 53 cents connection fee,

for longer calls it is worth the price, the quality is good and the call gets chareged direcly to your home phone bill (e.g. verizon), no plan, no additional monthly fee.

Can u please send info about your UCLA like how many kids get accepted there, and what degrees are offered there. Please send info to:

Kepner Middle School

You can choose a calling service based on reviews submitted by other customers at http://www.CallingBargains.com . I have found this website useful and easy to use. Available are reviews for most types of phone services (cellular, calling cards, etc), especially services from smaller companies.
