Ionian Islands with unlocked Three Mifi -
I will be visiting the Ionian Islands (Corfu, Lefkada, Ithaka etc) for a month twice a year, with my wifi-only iPad, and had thought of getting an unlocked Huawei E585 modem and a Greek SIM. The E585 only works on 3G. does anyone know whether this is the best solution (I will use a iPad navigation program that needs constant coverage but at very low download rates)? Which operator has the best 3G coverage in the Ionian?
