Who offers the best mobile phone coverage in Ireland?
Good phone signal is vital for calls, messaging and the internet; here’s how to find the best network coverage for your area and compare mobile plans in Ireland.
What mobile networks operate in Ireland?
There are three main Irish network operators:
All the other mobile virtual network operators (MVNOs) run services using one of the three main networks. You can check which MVNO runs on what network below.
| Mobile operator | Network | |
|---|---|---|
| An Post Mobile | Vodafone | |
| Clear Mobile | Vodafone | |
| GoMo | eir | |
| Lyca Mobile | eir | |

How to check outdoor coverage where you live
ComReg (The Commission for Communications Regulation) has created an outdoor mobile coverage map that makes it easy to check coverage and signal levels of all the networks at your Eircode.
You check coverage by 2G, 3G, 4G (voice calls, texts and data) and 5G (voice calls, texts and superfast data). Bear in mind that results aren’t guaranteed and are based on outdoor coverage only, which may differ from inside your home or office.
How good is 5G coverage in Ireland?
If you’re looking for superfast, real-time connections, 5G offers speeds up to 100 times faster than 4G, but it’s not as widely available in Ireland. Find out more about the benefits of 5G and whether it’s right for you in our guide How 5G works in Ireland.

Mobile coverage in Ireland FAQs
Do budget providers like GoMo, 48 have worse coverage?
No. Budget providers are Mobile Virtual Network Operators (MVNOs) so they do not own physical masts.
Instead, they rent space on the main networks. You get the exact same coverage and signal quality as the parent network, usually for a fraction of the price. Always verify your new budget provider’s network partner before switching.
Can I check the mobile signal at my specific address?
Do not rely on generic coverage claims or an operator’s own marketing maps.
The most reliable method is to use the official, independent ComReg Outdoor Mobile Coverage Map. By inputting your specific address or Eircode, you can view an unbiased breakdown of 2G, 3G, 4G, and 5G signal availability for every network at your exact location.
Why do I have a poor signal inside my house when outdoor coverage is supposedly 99%?
Network operators calculate their “99% population coverage” metrics based entirely on outdoor signals.
However, many other factors affect mobile coverage, including building materials, terrain, the number of users, and distance from the mast.
Indoor blackspots are rarely the network’s fault but are usually caused by factors such as building Insulation. Modern construction standards require foil-backed insulation, thick concrete blocks, and double or triple-glazed windows, all of which reflect and block mobile radio waves.
If you have a poor indoor signal but decent home broadband, ensure your mobile plan supports Wi-Fi Calling. This feature automatically routes your standard mobile voice calls and SMS texts over your home Wi-Fi network. .
