An update on the previous posts. Cosmote has just announced its first prepaid plans for data connection on computer. The plans are quite more expensive than the similar plans of Wind and Vodafone but I post them here in case there is only 3G coverage of Cosmote on the place you will visit.
COSMOTE Internet On The Go with Card
They offer 3 plans,
each with 1GB included volume, that differ on the connection time only. The 1-day plan costs 5€, the 7-day plan 10€, and the 30-day plan 30€. After 31 August 2010, they will cost 10, 14 and 50€, respectively.
You can get the
SIM pack for 20€ or the
Full Pack with 50€ (which includes USB modem) from any Cosmote or Germanos shop, activate and register the SIM and connect immediately. In case you need the connection settings for your own USB modem, the APN is "internet" and leave everything else blank.
