What’s the cheapest unlimited mobile plan?
The market currently crystallises around two standout rates: €12.99/month from 48 Mobile and Sky Mobile, and a fixed €15/month from Virgin Media. All three represent genuine unlimited data — no soft data caps, no throttling after a threshold — but they differ sharply on contract terms and price guarantees.
Sky Mobile €12.99 unlimited
According to Switcher.ie (comparison site aggregating Irish mobile deals), Sky Mobile sells unlimited data on the Three network for €12.99/month, locked at that rate for three years via a 12-month contract. The €12.99 price freeze means customers know exactly what they pay until mid-2029 — a rarity in a market where most providers build in annual increases.
48 Mobile €12.99 unlimited data
48 Mobile runs on the Three network and prices its prepay unlimited plan at €12.99/month with 5,000 minutes and 5,000 texts included. No contract means flexibility, but prepay users carry the risk of future price changes on 30-day notice. The 20GB EU roaming allowance is notably lower than several competitors at this price point.
Virgin Media €15 unlimited
Virgin Media offers unlimited calls, texts, and data for €15/month on a 12-month contract. The provider explicitly guarantees no price rises for life on this plan (Virgin Media). The offer ends 27 May 2026 (Virgin Media), and Virgin allows up to six mobile subscriptions per account — useful for family bundles.
The implication: 48 Mobile wins on monthly cost and no contract lock-in, but Virgin Media wins on price certainty over the long haul. Sky Mobile sits in between — cheap for three years, but the post-freeze rate is unknown.
Virgin Media’s €15/month is €2 more than 48’s rate, but it comes with a no-price-rise guarantee. For a two-year stay, that premium buys predictability worth roughly €24 over the contract — a calculation that flips if you expect to switch providers after 12 months.
What is the cheapest SIM in Ireland?
Cheapest is a loaded word here. “Cheapest SIM” can mean the lowest entry price, the best value per gigabyte, or the cheapest unlimited plan on a per-month basis. The answer shifts depending on which lens you apply.
LycaMobile prepaid SIMs
Lyca Mobile operates contract-free prepaid SIMs across Ireland on the Three network. Its Ireland Plus bundle runs €15 for 30GB data plus unlimited calls and texts — technically not unlimited data, but a competitive per-gigabyte rate for moderate users. Lyca also offers a true unlimited data prepay plan at €20/month (Lyca Mobile Ireland). The contract-free structure means no exit fees and no commitment.
48.ie value prepay
48 Mobile’s prepay unlimited at €12.99 undercuts most SIM-only alternatives. The trade-off is the 20GB EU roaming cap, which trails behind eir (65GB) and Tesco (36.95GB). For users who stay within Ireland, this is the strongest budget play.
eir SIM only €14.99
eir’s Connect 30-day SIM plan costs €14.99/month for the first 12 months, then reverts to €29.99/month without a broadband bundle (eir.ie). However, existing eir broadband customers receive a €10/month discount, bringing the rate to €9.99/month — the lowest entry point among major carriers for bundled households (eir.ie). eir adds a €9.99 SIM activation fee (eir.ie) and claims 99% 5G population coverage (eir.ie).
The pattern: 48 Mobile owns the pure prepay segment at €12.99, eir owns the broadband-bundled segment at €9.99, and Lyca Mobile sits between with contract-free flexibility at €15–€20. Activation fees (eir’s €9.99) can erase the price advantage of lower monthly rates on short-term stays.
What are the cheapest monthly phone plans?
Looking beyond unlimited-only plans, the monthly SIM-only market also includes high-value plans with significant roaming allowances and 5G access — particularly relevant for travellers and remote workers.
Virgin Media €15 for life
Virgin Media’s €15/month for-life offer is the standout long-term play. It includes unlimited calls, texts, and data on a 12-month contract with 37GB EU roaming per month (Virgin Media). The EU roaming figure is middle-of-the-pack compared to competitors, but the no-price-rise guarantee is unique at this price level.
eir €14.99 with 5G
eir’s Connect 30-day plan at €14.99/month includes unlimited data and 65GB EU roaming (Switcher.ie), positioning it ahead of Virgin Media on roaming volume. eir customers without broadband bundle pay €29.99/month after the initial 12-month period, so the long-term rate matters for anyone not switching after year one.
Lyca Go Unlimited €20
Lyca Mobile’s unlimited prepaid plan sits at €20/month with contract-free terms. The higher price relative to 48 Mobile and eir reflects Lyca’s lack of contract commitment and broader international roaming options on some bundles.
The implication: for travellers, eir’s 65GB EU roaming beats Virgin Media’s 37GB by a wide margin at roughly the same monthly cost — making eir the stronger choice for anyone who crosses the Irish Sea or heads to continental Europe regularly.
What is the cheapest but good phone plan?
Price alone doesn’t determine value. Data reliability, network coverage, and the transparency of fair usage policies all shape whether a “cheap” plan actually works for a given user.
Unlimited data reliability
Most unlimited plans in Ireland carry some form of fair usage policy. Switcher.ie notes that even plans marketed as unlimited may limit calls to two hours maximum per call (Switcher.ie). Data is genuinely unlimited on most plans covered here, but tethering restrictions vary and may affect heavy users who need hotspot access.
Network coverage factors
eir claims 99% 5G population coverage (eir.ie), the strongest coverage claim among the providers reviewed. Virgin Media and 48 Mobile operate on their respective networks — Virgin on its own infrastructure, 48 on Three. Three’s urban coverage is generally solid, though rural performance can lag eir in some areas.
Value under €20
At under €20/month, genuinely unlimited data exists in three confirmed forms: Virgin Media (€15 for life), 48 Mobile (€12.99 prepay), and Sky Mobile (€12.99 for 3 years). All represent genuine unlimited data with at least one included benefit beyond data — calls, texts, or EU roaming. Plans below these prices either carry data caps or represent prepaid bundles where unlimited means unlimited texts and minutes, not data.
The catch: “unlimited” data plans below €20 almost always carry contract terms or promo windows. Once a promo ends, the standard rate often doubles or more — Three charges €28–€35/month on its 12-month contract after promo periods (Three.ie), Vodafone Ultra rises from €20 to €35/month (Vodafone Ireland), and Tesco Elevate jumps from €10 to €30/month (Tesco Mobile).
Three applies a €2.50 annual price increase every April on its plans (Three.ie) — a compounding cost not visible in the headline promo rate but material over a two-year stay.
What network does ALDI Mobile use?
ALDI Mobile is a UK and German brand and is not a current provider in the Irish market. Irish consumers seeking comparable budget structures can look to Lyca Mobile (prepay, contract-free), 48 Mobile (prepay on Three), or Tesco Mobile (Clubcard perks), which together cover the main use cases that ALDI Mobile serves in other markets — low-cost prepay with straightforward pricing and no contract commitment.
Irish equivalents
Bonkers.ie (price comparison platform covering Irish telecoms) lists Tesco, GoMo, eir, and Vodafone as the most-searched SIM-only providers (Bonkers.ie), indicating where Irish consumers direct their comparison shopping when evaluating budget options.
Coverage comparisons
eir leads on 5G coverage claims at 99% population. Three’s network is the backbone for 48 Mobile, Lyca Mobile, and Sky Mobile, and is considered broadly competitive in urban areas. Virgin Media’s network is independent and may offer different coverage strengths depending on the user’s location.
Prepay network options
For users prioritising flexibility over price certainty, prepay options include 48 Mobile (€12.99 unlimited, Three network, 20GB EU roaming), Tesco Prepay Data Ultra 5G (€20 per 28 days, unlimited 5G data, 29.56GB EU roaming) (Tesco Mobile), and Lyca Mobile (contract-free unlimited from €20/month). All three run on the Three network or Tesco’s own infrastructure.
Why this matters: the Irish prepay market offers more genuine flexibility than most comparable European markets, but that flexibility comes with lower roaming allowances than some contract alternatives — a trade-off worth weighing for anyone who travels outside Ireland more than once a month.

Frequently asked questions
Are unlimited data plans truly unlimited in Ireland?
Most plans marketed as unlimited do offer genuine unlimited data without a hard cap, though fair usage policies may apply to specific services like tethering or extended voice calls. Call limits of around two hours per call on some plans have been noted by Switcher.ie. Always check the provider’s terms for tethering restrictions before committing.
What is the €15 SIM plan mentioned in this article?
The €15/month SIM-only plan is Virgin Media’s offering: unlimited calls, texts, and data on a 12-month contract with a guaranteed no-price-rise-for-life clause. It includes 37GB EU roaming monthly and the current offer ends 27 May 2026.
Do Irish providers offer senior discounts?
No formal senior discount programmes comparable to structures in the US market were found across the major Irish providers (eir, Three, Vodafone, Virgin Media). Some providers like Tesco Mobile offer loyalty discounts (Clubcard perks) that may indirectly benefit older or loyal customers, but these are not age-gated.
Is 48 Mobile good for coverage?
48 Mobile operates on the Three network in Ireland. Three’s urban coverage is broadly competitive, though eir claims broader 5G population coverage (99%). For rural users, checking Three’s coverage maps directly is advisable before committing to a 48 Mobile plan.
What are Bonkers mobile plans?
Bonkers.ie is an Irish price comparison site covering broadband, energy, and mobile. It does not sell plans itself but aggregates options from providers including Tesco, GoMo, eir, and Vodafone. It is useful for comparing SIM-only plans side-by-side before purchasing directly from a provider.
Can I get cheap unlimited on iPhone?
All SIM-only plans in this article work with any unlocked iPhone model. There are no iPhone-specific unlimited plans — pricing and data allowances are provider-level, not device-level. Ensure your iPhone is SIM-free or compatible with the relevant Irish network bands (most recent models support all major bands).
How does LycaMobile compare to eir?
LycaMobile runs on Three’s network; eir uses its own infrastructure. On price, eir (€14.99/month) and Lyca Mobile (€20/month unlimited) are close, but eir leads on EU roaming (65GB vs Lyca’s unspecified roaming cap) and claims stronger 5G population coverage. Lyca wins on contract freedom — no 12-month commitment versus eir’s contract requirement. Both are viable for different use profiles.
