Hi @Deirdre_62826 welcome to 3Community,
Has your service improved since posting? I've had a look and I see that we did have a site that was partially offline in Dunboyne recently, but the site is now back up and running. If you're still experiencing difficulties please try rebooting your phone and if you're still not picking up service please try manually selecting the network through your settings, for a guide on how to do this please click here and select your phone from the list.
