Three is Ireland's largest mobile network by subscribers, with nearly half the market. They've invested heavily in 5G and offer competitive plans, but their budget brand 48 often makes more sense.
Three at a Glance
| Feature | Details | |---------|---------| | Market Share | ~48% (largest) | | Price Range | €20-€50/month | | 4G Coverage | 99% population | | 5G Coverage | ~65% population | | Budget Brand | 48 |
Three's Plans
Bill Pay Plans
| Plan | Price | Data | Contract | |------|-------|------|----------| | Unlimited Max | €50/month | Unlimited 5G | 24 months | | Essential | €35/month | 30GB | 24 months | | SIM Only | €25/month | Unlimited | 12 months |
Note: Prices increase annually by CPI + 3%Prepay Plans
| Plan | Price | Data | Validity | |------|-------|------|----------| | All You Can Eat | €20/month | Unlimited | 28 days | | €20 Top-Up | €20 | Unlimited | 28 days |
Three's €20 All You Can Eat prepay is genuinely good value: unlimited data without fair use games.
The Good
1. Largest Network in Ireland
With 48% market share, Three has the most subscribers. This means ongoing investment and network improvements.
2. Strong 5G Rollout
Three has been aggressive with 5G in urban areas. Dublin, Cork, Limerick, Galway, and many towns now have 5G coverage.
3. Genuine Unlimited Prepay
Three's €20 All You Can Eat prepay offers unlimited data without the restrictive fair use policies of some competitors.
4. Solid Urban Coverage
In cities and large towns, Three's network is excellent, often the fastest available.
5. Multiple Options
From €20 prepay to €50 premium, Three covers various price points.
The Bad
1. Rural Coverage Gaps
Historically, Three has been weaker in rural Ireland compared to Eir. They've improved but gaps remain in remote areas.
2. Annual Price Increases
Like Vodafone, Three increases bill pay prices annually by CPI + 3%.
3. Budget Brand Is Better Value
Three's own budget brand, 48, offers better value:
- Three SIM Only: €25/month, unlimited
- 48: €12.99/month, 200GB 5G
Why pay nearly double for the same network?
4. Indoor Coverage Issues
Some users report weaker indoor signal compared to Eir and Vodafone, particularly in older buildings.
Who Should Choose Three?
Three direct makes sense if:- You want phone and in-store support
- You're financing a phone through them
- You prefer bill pay over prepay
- Your employer pays
- You want the best value (48 is cheaper)
- You live rurally (test coverage first)
- You want to avoid price increases
The Budget Alternative: 48
48 is Three's budget brand. Same network, much cheaper:
| Feature | Three | 48 | |---------|-------|-----| | Price | €25-50/month | €12.99/month | | Network | Three | Three | | Data | Varies | 200GB 5G | | Support | Full | Online only | | Contract | 12-24 months | Prepay/rolling |
48 offers better value for almost everyone. You get Three's network with more data (200GB vs unlimited, but who uses 200GB?) for half the price.The main 48 downside: roaming can be unreliable. If you travel frequently, this matters.
Three vs Eir vs Vodafone
| Factor | Three | Eir | Vodafone | |--------|-------|-----|----------| | Urban Coverage | ★★★★★ | ★★★★ | ★★★★ | | Rural Coverage | ★★★ | ★★★★★ | ★★★★ | | 5G Rollout | ★★★★ | ★★★★★ | ★★★ | | Budget Brand Price | €12.99 | €14.99 | €12.99 | | Budget Brand Speed | Full | Full | 5Mbps cap |
Verdict
Rating: 3.5/5Three is a solid network, especially in urban areas. But their budget brand 48 offers the same network for half the price.
Choose Three direct if: You need support or phone financing. Choose 48 if: You want Three's network at the best price (and don't travel often). Choose elsewhere if: You live rurally (GoMo/Eir better) or need reliable roaming (Clear Mobile/Vodafone better).---
Frequently Asked Questions
Is Three Ireland any good?
Three offers competitive pricing and good urban coverage with 5G. However, rural coverage is weaker than Eir/Vodafone, and customer service has mixed reviews. Budget MVNOs like 48 offer the same network for less.
Is Three or Vodafone better in Ireland?
Vodafone has better rural coverage and customer service. Three has more aggressive pricing and faster 5G rollout in cities. Choose Vodafone for rural areas; Three (or 48) for urban areas and value.
Why is Three coverage bad in rural Ireland?
Three has fewer masts in rural areas compared to Eir. Their network focuses on population density, so coverage is excellent in cities but gaps exist in countryside. Check their coverage map for your specific location.
Should I get Three directly or use 48 Mobile?
48 uses Three's network but costs €12.99/month for unlimited data vs Three's higher prices. Unless you need in-store support or specific Three perks, 48 is better value for the same coverage.
