when i move to philippines, i am thinking how secure will my internet be, such as internet banking,

when i first get there, the only connection available at the moment is smart bro 5 dongle connection,

are these safe secure?

or would i be advised to get something else, from what i am told, the equivelant of our internet, is a none wired hub,that transmits, where ours in uk is connected by wire through the phoneline,

advise appreciated
