Eir has advised that it is switching off its 3G network on a phased basis, starting in Donegal from 1 October 2026.
GoMo and Lyca Mobile use the Eir network, so this means that 3G services for its customers are also being retired. Customers can find out more on their websites:
- Eir;
- GoMo;
For those with a 4G or 5G-enabled smartphone or device, this change is not likely to affect you.
Older mobile devices that can connect only to 3G and 2G networks may be affected. You can 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.
There are a number of other types of devices which may no longer work once 3G has been phased out, for example card payment terminals and monitored care alarms. 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.
We have further advice and information on the 3G retirement.
