Mobile usage baskets:

In order to compare the various plans and tariffs offered the OECD's basket of mobile telephone services was used. The tariffs shown here represent the low usage basket, made up of approximately 30 short calls and 33 SMS messages per month. For more information on the baskets see the methodological annex of Hernan Galperin's Tariffs and affordability gap of mobile telephony services in Latin America and the Caribbean.

Currency conversions:
For the conversion of tariffs to USD the average exchange rate during the month of May 2009 as reported by bloomberg.com was used.

For the conversion of tariffs to purchasing power parity USD (PPP) the IMF's conversion rates were used.

Mobile Herfindahl-Hirschman Index:
The normalised Herfindahl-Hirschman Index (HHI) ranges from near 0 to 1. May 2009 data from Wireless Intelligence is used.  A HHI index below 0.01 indicates a highly competitive index, below 0.1 indicates an unconcentrated index, between 0.1 to 0.18 indicates moderate concentration, above 0.18 indicates high concentration. Costa Rica's monopoly mobile service provider gives it a HHI index of 1.0.
