Quick question:

I'm gonna be going thru London (for a day or so) thru to Italy for a couple weeks. I really want to get an internet stick, and since I can't figure out a price and plan on the Italian site, I want to know that if I buy an internet stick in London on Pay As You Go, can I then toss a Vodafone Italy SIM into it and use that? WITHOUT UNLOCKING it that is.

Thanks for your help!
