O2.ie isn't available at the moment

As O2 is becoming Three, O2.ie will be offline for 13 hours from 6p.m. on Sunday March 1st. Your MyO2 account and all its features will be automatically moved to Three.ie; so there's nothing you need to do. You'll soon be able to manage your account, upgrade, send webtexts and find the latest smartphones & deals on Three.ie. Sorry for the inconvenience.
