What is the best mobile phone plan in Ireland?
Best SIM-only plans
- Three’s €30 SIM-only plan offers unlimited data, calls, texts, and EU roaming — a strong choice for heavy users (Three Ireland).
- Vodafone Xtreme at €30/month includes free EU roaming and 5G access, but data speeds are capped after 60GB (Switcher.ie comparison).
- Tesco Mobile’s €15 Elevate SIM offers unlimited 5G data, any-network calls and texts, and 36.95GB EU roaming (Tesco Mobile).
Best bill pay plans with phone
- Vodafone and eir offer bundled phone+plan options, but prices vary by handset. For example, Vodafone Red plans start around €45 with a phone (Switcher.ie).
- Three’s bill pay plans typically include a 30-day flexibility and no long-term contract for the plan itself.
Best unlimited data plans
- Clear Mobile at €12.99/month for unlimited 5G data on Vodafone’s network — no fair usage policy in Ireland (Clear Mobile).
- Virgin Media Mobile at €15/month for unlimited data, calls, and texts, with no price increase for the lifetime of the plan (Virgin Media Ireland).
- Sky Mobile at €15/month (12-month term) with unlimited data, calls, and texts, and no fair usage limits in Ireland (Sky Ireland).
Which mobile network has the best coverage in Ireland?
Coverage maps by network
- ComReg provides an official outdoor coverage map that lets you check service at a specific address (ComReg Service Coverage Map).
- Vodafone leads with 99% 4G population coverage, followed by eir and Three with similar urban coverage (ComReg 2025 brochure).
- Clear Mobile, which runs on Vodafone, also claims 99% 4G population coverage (Clear Mobile).
Urban vs rural coverage
- In cities, all four networks deliver strong 4G and 5G signals. Rural areas show a gap: Vodafone and eir generally outperform Three, according to ComReg’s data.
- Virgin Media states its mobile service has 99% population coverage, though it uses Vodafone’s infrastructure (Virgin Media Ireland).
5G coverage availability
- Vodafone and Three have the most extensive 5G availability in urban areas; eir’s 5G is limited to select cities.
- ComReg notes that more providers are expanding 5G coverage throughout Ireland (ComReg).
Vodafone’s network is the most reliable by coverage, but it comes at a premium. If you live in a city, Three or Tesco Mobile (on Three’s network) will save you money without sacrificing signal strength.
The pattern: urban users can choose by price, but rural residents should prioritise coverage data over headline offers.
What is the cheapest mobile network in Ireland?
Cheapest SIM-only plans
- GoMo (eir sub-brand) offers the lowest advertised SIM-only price at €9.99/month for 200GB data (SmartSaver).
- Tesco Mobile’s €10 SIM-only plan is monthly rolling but includes only 5GB data, not unlimited (Tesco Mobile).
- Clear Mobile at €12.99/month and Virgin Media at €15/month are the cheapest unlimited-data SIM-only options (SmartSaver).
Cheapest unlimited data
- Clear Mobile €12.99 (unlimited 5G, no fair usage) — cheapest unlimited data plan in Ireland (Clear Mobile).
- Virgin Media €15 (unlimited, no price increase lifetime) — strong second option.
- Three €20 prepay unlimited data — good for those who prefer prepaid flexibility.
Prepaid vs contract cost comparison
- Prepaid plans (e.g., Three €20, Tesco Mobile €20 top-up) offer flexibility but often exclude EU roaming or 5G.
- Contract SIM-only plans (e.g., Virgin Media €15, Sky €15) lock in the price for the term but include EU roaming.
The cheapest plans often exclude EU roaming or 5G. Clear Mobile at €12.99 is a rare exception — it includes 5G and no fair usage, but roaming is limited to standard EU allowances.
What this means: budget-conscious users must check roaming and speed caps before committing to a low headline price.
Which is better, eir or Vodafone?
Pricing comparison
- eir is cheaper for basic plans — GoMo at €9.99 undercuts Vodafone’s cheapest SIM-only (€20 for 10GB).
- Vodafone plans include free EU roaming, while eir’s basic plans may charge extra for roaming.
Coverage comparison
- Vodafone has better overall coverage, especially in rural areas, with 99% 4G population coverage (ComReg map).
- eir and Three have similar coverage in cities, but eir trails in remote rural spots.

- Switcher.ie notes that eir’s customer support wait times are longer than Vodafone’s.
What is the Three €30 plan?
What’s included?

- 30-day rolling contract — no long-term commitment.
- 5G access where available.
How does it compare to similar plans?
- Vodafone Xtreme at €30 also includes unlimited data but with a 60GB speed cap after which speeds reduce.
- eir Unlimited at €30 includes 5G and EU roaming but with a 50GB fair usage limit.
- Three’s plan is the most transparently unlimited — no cap on data quantity, only a speed throttle after 60GB in some cases.
Pros and cons
Upsides
- True unlimited data with no hard cap in Ireland
- EU roaming included (35-60GB)
- 30-day rolling contract
Downsides
- Speed throttled after 60GB on some plans
- Coverage weaker in rural areas compared to Vodafone
- No phone subsidy — SIM-only only
The implication: Three’s €30 plan is the clearest unlimited option for city dwellers, but rural users should check coverage first.
Comparison table: Unlimited data SIM-only plans
Five unlimited plans, one pattern: the cheapest ones often lack 5G or EU roaming, while the premium ones guarantee speed and coverage.
| Provider | Monthly price | Data limit | EU roaming | 5G | Contract length |
|---|---|---|---|---|---|
| Clear Mobile | €12.99 | Unlimited | Standard EU | Yes | 30-day rolling |
| Virgin Media | €15 | Unlimited | Standard EU | Yes | Lifetime fixed price |
| Sky Mobile | €15 | Unlimited | Standard EU | Yes | 12-month |
| Tesco Mobile Elevate | €15 | Unlimited | 36.95GB | Yes | 12-month |
| Three | €30 | Unlimited | 35-60GB | Yes | 30-day rolling |
| Vodafone Xtreme | €30 | Unlimited (60GB cap) | Unlimited | Yes | 30-day rolling |
| eir Unlimited | €30 | Unlimited (50GB FUP) | 25GB | Yes | 30-day rolling |
The implication: the cheapest unlimited plans (Clear Mobile, Virgin Media, Sky) are excellent for urban users with moderate data needs, but heavy streamers or rural residents may need the premium networks.
Spec table: Key plan features
Six categories, one takeaway: the fine print on speed caps and EU roaming matters more than the headline price.
| Feature | Clear Mobile | Virgin Media | Sky Mobile | Tesco Mobile | Three | Vodafone | eir |
|---|---|---|---|---|---|---|---|
| Base network | Vodafone | Vodafone | Three | Three | Three | Vodafone | eir |
| 5G included | Yes | Yes | Yes | Yes | Yes | Yes | Limited |
| Speed cap | None | None | None | None | 60GB throttle | 60GB throttle | 50GB FUP |
| EU roaming data | Standard EU | Standard EU | Standard EU | 36.95GB | 35-60GB | Unlimited | 25GB |
| Fair usage in IE | No | No | No | Yes | Yes | Yes | Yes |
| Contract length | 30-day | Lifetime fixed | 12-month | 12-month | 30-day | 30-day | 30-day |
| Price guarantee | No | Yes | Yes | No | No | No | No |
The trade-off: unlimited data with no fair usage is rare — Clear Mobile and Virgin Media are the only ones offering it without a cap. If you’re a heavy user, these are the safest bets.

Quotes from the experts
“Vodafone continues to have the highest 4G coverage, reaching 99% of the population.”

Frequently asked questions
How often do mobile plan prices change in Ireland?
Prices can change at any time, but many providers offer price guarantees for the contract term. Virgin Media and Sky, for example, guarantee no price increase for the lifetime of the plan. Always check the terms before signing.
Can I keep my phone number when switching providers?
Yes. Under Irish regulations, you can port your number to any other network. Request a PAC (Porting Authorisation Code) from your current provider to start the process.
What is the cheapest plan for light users (fewer than 2GB per month)?
GoMo’s €9.99 plan with 200GB is overkill but still the cheapest. For truly light use, a prepay option like Tesco Mobile’s €10 for 5GB or eir’s prepay bundles around €10 may be better.

Yes. Most plans now include 5G at no extra cost. Clear Mobile, Virgin Media, Three, and Vodafone all include 5G in their standard SIM-only plans. eir’s 5G is limited to certain postcodes.
How do family mobile plans work in Ireland?
Vodafone offers family multi-SIM discounts, but most networks do not have a dedicated family plan. The best approach is to sign up each family member on a separate SIM-only plan and use a shared billing account where available.
Are there any hidden fees in low-cost SIM-only plans?
Some low-cost plans charge for EU roaming over the allowance, charge for exceeding fair usage limits, or increase the price after the promotional period. Clear Mobile and Virgin Media are among the most transparent with no hidden fees.
What is the best mobile network for rural communities?
Vodafone leads in rural coverage, followed by eir. Three and its MVNOs (Tesco Mobile, Sky) are weaker in remote areas. Check ComReg’s coverage map for your specific address before committing.
