Yes you do as it is not part of your allowance. Data roaming means you have to pay international rates. Data is £1.99 a day, I suggest turning mobile data off then you won't face a large bill. Calls are 35p a minute I think. Text are 8p to send, free to receive. You should receive a text when you arrive informing you of the prices
