Usb Flash Drive Wireless Internet in Kythira: Cosmote or Vodaphone?

If you are planning to stay in Kythira for long periods of time, you may want to use a continuous source of internet connexion, one you can use everywhere on the island. Well, almost everywhere.
I tried USB flash drives from both Cosmote and Vodaphone. While the Cosmote is easy to install and use on a MAC, it does not work everywhere on the island. I actually discovered that is is pretty limited in range and in signal strength. The same device from Vodaphone is a much better choice as it allows you to get a strong signal in a wider range of areas on the island. It is a bit trickier to install on a MAC but once you figure it out (with the help of Vodaphone Tech Support) you will be all set. The contract for illimited access runs about 50 euros/month for either service. You can set up an automatic payment with your Greek bank account so you don't have to run to the IP provider store to pay your bill every month.
