The rural rule
Ask a neighbour which network they can actually use in the kitchen, not on the road into town. Walk your own rooms with Wi-Fi off. Then stop shopping brands. If Three works, take 48 at €12.99. If Vodafone works, take Clear. If Eir works, take GoMo.
Eir’s advertised 5G population figure is the widest of the three. That is still a population claim, not a guarantee at a house down a boreen. Full network explainer: best mobile network in Ireland.
The three radios, and the cheap SIM on each
| Host radio | Owns the masts | Advertised coverage | Cheap unlimited | From |
|---|---|---|---|---|
| Eir network | Eir Mobile | 99% population (own 5G network) | GoMo | €12.99 · Rolling monthly |
| Three network | Three | 99% population (own network) | 48 | €12.99 · Rolling monthly |
| Vodafone network | Vodafone | 98% population (own network) | Clear Mobile | €12.99 · Rolling monthly |
48 posts a plastic SIM with no activation fee. GoMo has eSIM. Clear and GoMo each add a €12.99 activation fee. None of that changes which mast you can hear.
What fails in the countryside
- An Post as "rural coverage". It is Vodafone 4G with a post-office top-up. Virgin Media and An Post Mobile have no 5G on the plans we list.
- Paying Three or Eir retail for extra masts. 48 and GoMo use the same radios. Freedom and Connect are teasers that jump.
- Lycamobile "unlimited" as a rural data pipe. After 100 GB it is 256 kbps. Fine for calls home. Poor as a house hotspot.
- A Dublin 5G map. Indoor stone and distance to the mast still win. Test the phone, not the brochure.
How to check before you switch
- Borrow a phone on each host, or stand in the yard with Wi-Fi off on yours.
- Try the rooms you actually use, and the road to work or school.
- Order the cheap SIM on the winner. Tick keep my number. Keep the old SIM live until the new one works.
Switch steps: how to switch mobile. Cheap unlimited three-way: 48 vs GoMo vs Clear. 5G vs 4G: 5G in Ireland.
