Mobile networks in Ireland
In Ireland, the mobile market is built on three main infrastructure owners, known as Mobile Network Operators (MNOs) and eight active Mobile Virtual Network Operators (MVNOs).
While you might see many different names on your phone screen, they all run on one of the three physical networks.
Mobile Network Operators (MNOs)
These companies own the actual cell towers and radio masts across the country.
Mobile Virtual Network Operators (MVNOs)
These providers “rent” network capacity from the big three above. Some are independent companies, while others, such as Clear Mobile and GoMo, are owned by the MNOs to target budget-conscious customers.
| On Vodafone Signal | On Three Signal | On eir Signal | |
|---|---|---|---|
| Clear Mobile | 48 | GoMo | |
| An Post Mobile | Tesco Mobile | Lyca Mobile | |
| Sky Mobile | Virgin Mobile |
Which Irish networks offer 5G?
The availability of 5G in Ireland is now good. Most budget-friendly operators like GoMo and 48 now include 5G as standard, while some independent MVNOs still treat it as a premium add-on or don’t offer it at all.
| Provider | 5G Availability | |
|---|---|---|
| Vodafone | Included as standard | |
| Three | Included as standard | |
| eir | Included as standard | |
| GoMo | Included as standard | |
| 48 | Included as standard | |
| Sky Mobile | Included as standard | |
| Clear Mobile | Included as standard | |
| Lyca Mobile | Included as standard | |
| Tesco Mobile | Specific 5G plans only | |
| An Post Mobile | 4G only | |
| Virgin Mobile | 4G only |
To use 5G, you need a 5G-enabled handset and you must be in a 5G coverage area. Even if your plan says “5G,” your phone will drop back to 4G in rural areas where the 5G signal hasn’t reached yet.

When you’re comparing networks and plans, think about:
If you’re unsure how much data you really need, check your mobile phone account to see how much you normally use each month. It may be lower than you think.
