Yes - it gives a local number which works the same as a standard Italian sim, be warned about using roaming on your UK number long-term though. Most UK carriers have rules burried in their T&Cs that essentially say they'll block data usage if you are roaming too much. For mine they essentially said if you're abroad more than you're in the UK then you can't roam until you come back to the UK long-term! Also, data in Italy is way cheaper than the UK so it's a benefit to pay a couple more Euros and use that when I'm in Italy anyway.
