A year on one screen. Atlantic 12 costs €49, below the €59–75 that twelve-month offers for Irish IPTV usually ask online at the time of writing. Divided by twelve, that is €4.08 a month, or 13 cent a day. Atlantic 24 goes lower again per month, €3.71, if you are happy to pay for two years at once.
Where we are not the lowest. Atlantic 3 at €29 sits above the €24–25 seen for three months elsewhere. It is there for a season, not as the cheapest way in; per month, the year costs less than half as much as the short plan.
Two TVs. Two screens at the same time cost €79 for twelve months on Atlantic 12 Duo, against about €100–130 seen online: €6.58 a month for the pair, 11 cent a day per screen.
Against pay TV. A pay-TV package with sport and films can come to €80 a month or more at the time of writing, usually on a 12- or 18-month contract. A year of that is at least €960; the same year of IPTV Ireland on Atlantic 12 is €49, paid once, with nothing to cancel at the end. Because IPTV in Ireland runs on the broadband and the devices you already have, the Line check matters as much as the price.
What a very low price can leave out. Whoever you order from, these are reasons to stop and ask questions before paying:
