Estonia offers unlimited Wi-Fi/GPRS for as little as US$20: Veljo Haamer of Wifi.ee in Estonia (one of the Baltic republics for the geographically challenged) writes in reaction to the Czech Republic service offering unlimited GPRS service for US$34 per month that three Estonian wISPs have flat rate monthly GPRS and Wi-Fi service. The least expensive plans are US$20 per month from RadioLinja and Vodafone.
Veljo also points us to a coverage map in English of Wi-Fi service, of which 50 percent are still free. This is another clear sign of how in a country (or area) with less copper infrastructure how Wi-Fi or unlicensed wireless can transform connectivity, and hopefully enlarge the economy.
My family is mostly from Lithuania and areas of Russia and Poland near there, so Estonia has a warm spot in my heart.
