Key takeaway
A comparison of the best prepaid and monthly SIM card options for people who have just arrived in Ireland — no contract needed.
Your options as a new arrival
When you first arrive in Ireland, you have two main options: a Pay-As-You-Go (PAYG) SIM with a prepaid bundle, or a SIM-only monthly plan. PAYG is easiest to get started — no contract, no Irish address needed, available to buy in minutes from most shops. Monthly plans are cheaper per month but typically require an Irish bank account or address.
Three Ireland — best overall for data
Three consistently offers some of the best value data plans in Ireland. Their prepay All in One bundles give generous data allowances for €15–€25 per month. Three has strong 5G and 4G coverage in Dublin and major cities. Their network can be weaker in very rural areas. PAYG SIMs available from Three stores and many convenience stores.
GoMo — cheapest monthly plan
GoMo (runs on Eir's network) is frequently the cheapest option for a monthly SIM-only plan. Their unlimited data plans are competitively priced and run month-to-month with no long-term contract. You need an Irish bank account to set up a monthly plan. Coverage is good across most of Ireland thanks to Eir's extensive network.
Vodafone — best for rural coverage
Vodafone has the most extensive rural coverage in Ireland. If you're living outside a major city, Vodafone is often the most reliable choice. Their PAYG bundles and monthly plans are slightly pricier than Three or GoMo, but the coverage reliability is worth it in many areas.
48 — best for flexibility
48 (runs on Three's network) offers very flexible monthly plans that you can change or cancel with no penalty. Good for people who aren't sure how long they'll be in Ireland or who want flexibility without committing to a contract.
Where to buy
PAYG SIMs are available from: operator stores, Centra, Spar, Tesco, Dunnes Stores, Aldi (their own Three-network SIM), and most newsagents. You can also order online for next-day delivery if you have an Irish address ready.
