Ireland's landline telephone service is still dominated by Eircom - the ex state provider. The telephone service was deregulated a few years ago - and the introduction of some competition has helped to bring prices down.

Vodafone Ireland is now one of the biggest competitors to Eircom - they have taken over Perlico and BT Ireland.
Their package of phone line and upto 8Mb broadband is a pretty good offer.
It costs €45 a month . This includes Unlimited local and national calls at anytime ; 8MB always-on broadband. and Line rental . The package includes 200 free minutes of calls each month to vodafone mobiles. For Vodafone Mobile pay monthly customers - you get a 5% discount on this price .

Mobile phone networks

Mobile operators in Ireland include Meteor ; Three ; Vodafone and O2

Tesco also operate a mobile phone network (Using the O2 network)
They all have a raft of various packages and deals to suit everyone. You can choose a pay monthly package or go for a Pay as You Go option where you buy credit in advance.

The cheapest mobile calls will depend on exactly how and when you use your phone - but if you are a fairly heavy user - more than 300 text messages a month and 400 minutes of calls - then Three Ireland have very good package thay should suit most people.
The Three Ireland Classic Flex Sim Only package gives you 500 "units" a month for €35 . A single unit will get you 1 minute worth of calls or 2 text messages. They also throw in a free "add on" - the best of these is free anytime calls to Irish landlines.
You just get the SIM - no new phone needed and the contract is just for 30 days . Visit Three to see more

Three are also looking good on their Pay as You Go deals - if you top up by €20 - they give you another €10 free credit and unlimited texts to any network at any time PLUS free weekend calls to any network.

Someone on the 3 Pay tariff - topping up by €20 could send 1000 text messages (or more) in a month and make 100 minutes of calls for the price of €20. (Even more calls if you make them at weekends!)

Compared with other Pre Pay tariffs - the same usage would cost €34.66 on Meteor, €35.70 on O2 Experience More , €36.04 on Vodafone (Free any Network Texts).
With Tesco's offer of double your credit - you would end up spending about €80 for this amount of texts and calls.

(Figures taken from Call Costs - they spread calls proportionately across times of the day and networks and landlines)
