Make a table rating the 5 cheapest phone cards, as indicated in
medicalcountries.org. Indicate the cost, to call to & from, Chicago,
to & from London, Mumbai, Bangkok, Budapest, and   N.Y.  City.
Indicate how the card companies would round the time, monthly fees,
connection fees, maintenance fee, minimum usage fees, expiration date,
hidden costs, additional fees for smaller purchasers, whether you can
call from some numbers without putting in a pin number, and any
unusual contract terms. Use your creative ability to indicate what a
card user would need to notice to get the best deal, and give us your
advice, or comments. A person in a high medical cost country may need
to telephone another low cost country, for their medical needs.
