This is an app where you can get for a small fee about (€5 per month) an Irish mobile phone number with unlimited texts and Calls to other Irish phones. If you are worried about being nabbed by the pigz on the way out of an apartment, you could immediately delete it from ypur main phone.
There are others out there as well.
