Hi,
Have had Smart for a week now. Easy setup following clear instructions. On Crown Alley exchange from time of registering on Smart's website to going live was a little over 3 weeks. Seamless change of number and phone service from Eircom. Very happy with the service. Good speeds and no downtime so far. I would suggest if you have to wait to get Smart do so as it is like very good value for money for a top class service.
