Mobile phone roaming

[Gittle]

As many of you probably know by now, I am in Dublin for a holiday/study junket. I have local mobile service through Vodafone; I have not used up that much credit (unfortunately, I have not had many women to call :(), so I plan on using it when I go over to London. The question is, is it worth maintaining the service after the credit runs out (i.e., topping up the ROI mobile account in the UK, which is possible), or should I get local service, even though I will only be there for about three days?

I hope to view all of your responses, although I may not reply immediately because my online options are limited at the moment.

Well you can buy cheap o2 sim cards for £5 over here which give you free texts and calls with a £10 top up, but if you're not going to use all the extras and the credit it might not be worth it.
