Their customer service is abysmal. I was looking to switch to try to save money and thankfully I tried the 15/month pre-pay first on a spare phone. Nothing works. They say you'll get emails with codes and PINs, you won't. They say you'll get your SIM in 5 to 7 working days, you won't. You'll get 15GB of "local data" which means you can't tether other devices to your phone, your "Personal Hotspot" option won't appear. "All national calls" is all mobiles and landlines in Ireland but excludes the premium rate lines, 1890, 1850, etc.
