sorry but this might be a dumb and stupid question. when you guys say an unlocked phone... what exactly does that mean?

Some questions to consider:

<span style='color:blue'>1. Will YOU be making calls out and to where?</span>
Maybe some but within Greece nothing International
<span style='color:blue'>2. Do you want people in US to call you?</span>
YES
<span style='color:blue'>3. It will be cheaper for you to have your family reach you at a land line rather than on your cell phone.</span>
<span style='color:blue'>4. It will be cheaper for your family to reach you via SMS than calling you on the cell phone.</span>
<span style='color:blue'>5. Will you be doing SMS?</span>
SOME
<span style='color:blue'>6. Will you have access to a computer?</span>
Not sure, I am debating whether to bring my laptop but I am unsure of internet access
<span style='color:blue'>7. How long will you be away</span>
1 month

Thanks to all for the input.
