Best Mobile Phone Plans Ireland: Cheapest Unlimited Deals

Irish phone plan prices have collapsed in recent years, with several providers now fighting hard for unlimited-data customers at genuinely low prices. Clear Mobile and Sky Mobile both launch at €12.99 per month, for example — figures that would have seemed impossible a few years ago. This guide cuts through the noise: we’ll rank the main providers by price and coverage, walk through the cheapest unlimited options, and give you a practical framework for choosing the right plan.

Cheapest unlimited plan: €12.99/month (Clear Mobile, Sky Mobile) · Best fixed-price deal: €15/month for life (Virgin Media) · Top comparison sites: switcher.ie, bonkers.ie · Prepay leader: Lycamobile contract-free

Six providers now compete directly on unlimited data, with prices clustering between €12.99 and €15/month — but contract terms, roaming allowances, and network infrastructure diverge sharply.

Who is the best mobile phone provider in Ireland?

“Best” depends on what you value most — price, coverage, or feature extras. Switcher.ie (Ireland’s leading mobile comparison platform) aggregates SIM-only and bill pay deals from all major providers, making it the first stop for most shoppers. Tesco Mobile has built a loyal base by promising no mid-contract price increases, a promise that matters more than it sounds when you’re locked into a 12- or 24-month deal.

Top providers like Tesco Mobile and switcher.ie

Switcher.ie lists plans across SIM-only and bill pay categories, letting you filter by data allowance, contract length, and price. Tesco Mobile distinguishes itself with its loyalty promise: no mid-contract price hikes. The platform also tracks prepay options from Lycamobile and other MVNOs (mobile virtual network operators).

Factors: price, data, coverage

The three variables that matter most: monthly cost, whether data is truly unlimited or capped, and network coverage where you live and work. Bonkers.ie (an independent Irish consumer finance comparison site) notes that the best plan ultimately depends on your specific needs across these dimensions.

What is the best unlimited plan for cell phones?

Unlimited plans have become the standard offering across Irish providers, but “unlimited” comes with fine print. Some plans cap your data at high volumes before throttling, others include fair usage policies that limit hotspot use or international calling. The market leader for new customers is GOMO, which offers 5G unlimited data at €14.99 per month — a price that undercuts many legacy deals.

GOMO €14.99 unlimited 5G for new customers

GOMO (a GoMo-branded sub-brand) provides unlimited data prepay at €20 top-up every four weeks on the Vodafone network, which Switcher.ie identifies as delivering 99% 4G population coverage in Ireland and 5G in selected areas across all 26 counties. The prepay model means no contract — you top up monthly or walk away anytime. EU roaming is capped at 75GB under fair usage terms.

Lycamobile unlimited data options

Lycamobile offers prepaid SIM-only plans with unlimited data and EU roaming included, according to Lyca Mobile Ireland. The appeal: no contract, no credit check, and a straightforward top-up model. However, Lycamobile’s data speeds and customer service ratings trail the major networks in some user-reported benchmarks.

Is eir or Vodafone better?

The eir vs Vodafone question comes down to two factors most Irish consumers care about: coverage and price. Both networks have expanded 5G aggressively — eir claims 99% 5G coverage across Ireland, while Clear Mobile (which runs on Vodafone) reports 99% 4G population coverage with 5G rolling out.

eir vs Vodafone coverage

eir operates its own network infrastructure, which gives it more control over rollout pace and quality. According to eir’s official site, its 5G network covers all 26 counties. Vodafone, which hosts MVNOs like Clear Mobile and GoMo, covers 99% of the population on 4G with selected 5G areas. Real-world speed tests vary by region and device, but eir’s infrastructure generally scores well in Ireland network speed test benchmarks.

Price and data comparison

eir SIM-only starts at €14.99/month for unlimited 5G data, or €9.99/month if you’re an existing eir broadband customer (a €10 discount applied to all mobile plans). On the other side, Clear Mobile on Vodafone offers unlimited 5G at €12.99/month — the cheaper option, but with prepay terms rather than a fixed contract.

Which network has the strongest signal?

Coverage quality in Ireland has converged significantly, but real-world performance still varies by postcode. Uswitch (a UK comparison platform with Irish mobile coverage data) provides crowd-sourced coverage maps that supplement the self-reported figures from providers.

Coverage maps from Uswitch

Uswitch aggregates user-reported speed and coverage data, giving a ground-level view of network performance that supplements official provider claims. Their Irish data shows strong 4G coverage from all three backbone networks in urban centers, with more variable performance in rural Connacht and Munster.

Ireland vs UK networks

Irish networks have narrowed the gap with UK equivalents. eir claims “Ireland’s No.1 5G network” and Three Ireland’s SIM-only deals are marketed as among the best in Ireland, though direct speed comparisons between the two markets require postcode-level analysis. The key takeaway: Irish consumers now have access to 5G speeds that rival UK urban centers, though rural rollout remains uneven.

What are the cheapest monthly phone plans?

The cheapest plans cluster around €12.99-€15/month for unlimited data, according to Switcher.ie (which tracks pricing across the Irish market). But “cheapest” has nuances: some providers offer low entry prices that rise after a promotional period, while others lock in rates for life.

SIM-only deals on switcher.ie

Switcher.ie lists SIM-only plans from providers including Tesco Mobile, GoMo, eir, and Vodafone. Their comparison tool lets you filter by monthly cost, data cap, and contract type (12-month vs prepay). The cheapest entry-level unlimited deal on their platform: Clear Mobile at €12.99/month on the Vodafone network.

How to lower your phone bill

Three strategies work consistently: (1) Switch to SIM-only if you’re on a bundled phone+plan deal — SIM-only often costs half what you’d pay for the equivalent data with a new device included. (2) Bundle with your broadband provider — eir offers €10 off mobile plans for existing broadband customers. (3) Choose prepay if you want flexibility — Lycamobile and GoMo offer contract-free unlimited plans that let you walk away anytime without early termination fees.

The pattern: Sky and Clear win on entry price, Virgin Media wins on permanent pricing, eir wins if you already have their broadband, and GoMo wins if you need maximum EU roaming data (75GB) on a prepay model.

Comparison: Key Features Across Providers

Six providers, three price tiers, and one consistent pattern: the cheapest unlimited plans all cluster between €12.99 and €15/month, but the details diverge sharply on contract terms, roaming allowances, and network infrastructure.

The comparison makes the trade-offs concrete: Sky Mobile offers the lowest entry price but eventually matches Virgin Media’s permanent rate. GoMo’s prepay model costs more per month but includes the highest EU roaming allowance. eir’s broadband discount effectively undercuts Clear Mobile’s entry price for existing customers.

How to Switch Providers: A Step-by-Step Guide

Switching mobile providers in Ireland is straightforward if you know the steps. The process typically takes 1-5 business days for number porting, and most providers handle the technical side for you.

Step 1: Check coverage in your area

Before anything else, verify that your chosen network covers where you live, work, and travel. Use Switcher.ie or Bonkers.ie to check coverage maps by address. If you’re switching from one backbone network to another (e.g., from Three to eir), this step is especially important.

Step 2: Choose your plan type

Decide between SIM-only (no device) or bill pay (device included). SIM-only typically halves your monthly cost for equivalent data. If you need a new phone, compare the total cost of a bill pay plan against buying a device outright and pairing it with SIM-only. The Google Pixel 6 review on Reefwatch shows mid-range handsets pair well with budget SIM-only plans.

Step 3: Compare prices on Switcher.ie or Bonkers.ie

Use an aggregator like Switcher.ie or Bonkers.ie to compare plans side-by-side. Filter for your preferred network, data allowance, and contract length. Note any activation fees — Clear Mobile charges €12.99, and some connect plans charge €14.99.

Step 4: Check the offer end date

If you’re targeting Virgin Media’s €15/month for life deal, the offer ends 27 May 2026. Sky Mobile’s €12.99 deal holds for 36 months before rising to €15. Factor these timelines into your decision if price certainty matters to you.

Step 5: Port your number (or don’t)

Number portability is standard in Ireland — Virgin Media SIM-only includes easy number porting, and most providers support it. If you want to keep your existing number, your new provider handles the porting process. Allow 1-5 business days.

Step 6: Watch for early cancellation fees

Early cancellation fees apply on 12-month contracts. Calculate whether the savings from switching outweigh the exit fee. If you’re out of contract, switching costs you only the activation fee at your new provider (typically €12.99-€14.99).

“No price rises, ever. That’s right this SIM Deal is For Life!”

— Virgin Media (Virgin Media official site)

“Freeze your bill for 3 years with Sky Mobile. Customers can now avail of Sky’s Unlimited plan for just €12.99 a month for 3 Years.”

— Switcher.ie (Switcher.ie comparison platform)

“Enjoy Ireland’s No.1 5G network availability from €14.99/month.”

— eir (eir.ie provider site)

The Irish mobile market is genuinely competitive right now — the irony is that most consumers pay more than they need to because they never run the comparison. For budget-conscious shoppers, the choice is straightforward: Clear Mobile at €12.99/month or Sky Mobile at €12.99 for three years give you the lowest entry point on unlimited data. For long-term stability, Virgin Media’s €15/month for life deal is the only genuinely permanent price lock in the market — and that offer expires 27 May 2026.

For Irish consumers who travel frequently in the EU, GoMo’s 75GB roaming allowance on prepay is the standout option. For rural users who need guaranteed coverage, eir’s 99% 5G network claim and existing broadband discount make it the safer bet, even at a slightly higher price.

Cheapest unlimited deals hit €12.99 from Clear Mobile and Sky, though best mobile plans Ireland coverage reveals Lycamobile undercuts at €10 monthly.
