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 Three  
Sky Mobile Vodafone  
Tesco Mobile Three  
Virgin Mobile Three  
48 Three  

You’re likely to get the same coverage from these MVNOs as the network they’re run off. So, it’s worth shopping around to find a deal that works best for you and your location.

Which network has the best mobile coverage?

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 can also check

  • 2G (voice calls and texts)
  • 3G (voice calls, texts and data)
  • 4G (voice calls, texts and data)
  • 5G (voice calls, texts and superfast data)

Bear in mind that results aren’t guaranteed and are based on outdoor coverage, which may be different from inside your home or office.

Why do some areas have poor network coverage?

Vodafone, Three and Eir, offer up to 99% 4G population coverage in Ireland, but this still leaves some people struggling for a good mobile connection.

There are lots of factors that affect mobile coverage; some of these include:

  • Building materials: Some materials used in walls and insulation can affect signal strength. You can use WiFi call or mobile phone repeaters to increase signal.
  • Terrain: Places with mountains and valleys tend to be blackspots because they’re more remote and signals are obscured.
  • Density of users: A high volume of people using their mobiles at the same time and location will slow a connection.
  • Distance from the base station: The signal has to pass from you to the connecting base station, so the closer you are, the better the signal.
  • Your handset: The higher the TR/P (Total Radiated Power), the better the reception.

5G mobile

What about 5G coverage?

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.

To find out if it’s been rolled out in your area, you can use this coverage map to check your network, or go to these mobile providers directly:

How to choose a mobile network

Here are a few things to help you get started:

  • Enter your Eircode in the outdoor mobile coverage map to check which network signal is the strongest
  • Check the 5G coverage in your area if you’re looking for a faster service
  • Consider where you use the phone most, for example, you may need to check coverage at your office
  • Consider what you use the phone for most, for example calls or data, and check call charges
  • Ask for recommendations from family, friends and neighbours living in the same area
  • If you are in a known blackspot, make sure your handset has a high TRP

If you find that the coverage is poor when you switch providers, you should be protected by a 14-day cooling-off period.

Some networks like Vodafone offer a network satisfaction guarantee so you can cancel within 30 days and get your money back. Always check the full terms before signing up.

Get a SIM only deal with the calls, texts and data you need for less.

It only takes a few minutes to find a cheaper deal and start saving.
