thanks chaps, i want to get as much as i can sorted before i go so i don't have to worry about it.
so, i'm looking at buying:
a) CallYa (Voda) SIM for France and Switzerland
b) a Three SIM (which i will disable auto network selection on) and use it if i get 3 reception and look to add the 'broadband addon'
Now, for WIND, what would the implications be of buying a SIM card off ebay, such as:

Would it work? How would i topup?
