Mobile service providers are gradually phasing out their 3G networks and will continue to do so in the coming months and years. This will allow the providers to focus on increasing the deployment of more advanced technologies, 4G and 5G.
Eir has announced that it will begin switching off its 3G mobile network in Ireland on a phased basis from October 2026. Eir will contact customers directly who are currently using 3G-only services, with guidance on the steps required. This may include updating device settings, replacing a SIM card free of charge, or moving to a compatible device.
GoMo mobile and Lyca mobile use the Eir network, so this means that 3G services for its customers are also being retired.
Vodafone switched off its 3G network in October 2024. Clear Mobile and An Post use the Vodafone network, so this means that 3G services for its customers are also retired.
Each mobile service provider will begin this retirement process in their own time, and consumers will be notified by their provider in advance of any planned changes to their service.
Older mobile devices that can connect only to 3G and 2G networks will continue to make and receive phone calls over the 2G network, but data services will be affected. This means your ability to connect to the web (via apps and browsers, etc.) will be slower.
For those with a 4G or 5 G-enabled smartphone or device, this change is not likely to affect you.
Your mobile provider might contact you in due course to let you know if you are affected and what steps you need to take. You should check with your mobile provider for the latest updates and news on their plans to retire 3G.
The retirement of 3G services means mobile providers will have more resources to improve both their 4G and 5G networks. Both 4G and 5G provide faster internet speeds, better signal quality and improved mobile service for customers.
If you are using an older device that doesn’t support 4G or 5G, you may need to get a new handset if you wish to continue using mobile data services.
Older devices will continue to support data services on the 2G network but with much slower data speeds. Your mobile provider may be in contact to offer you an upgrade or you can get in touch with them to find out what they can do to help.
Mobile devices are not the only devices affected by the 3G network retirement. Here we have listed a number of types of devices which may no longer work once 3G has been phased out. To ensure your device continues to work following the phasing out process, or to see if you need to upgrade or to purchase a new SIM, we advise checking your device or contacting your supplier.
