I know on boards.ie it was discussed and debated as to cheaper option available. But for me it would be a no brainer to move my wife onto it when her contract is up. €25 for everything unlimited. Be aware though it is not a 4g offering on the data. However my wifes plan doesnt have 4g anyway.
Also it is an MVNO piggy-backing on 3/o2's network so there should no real coverage issues. Just depends how they normally are in your locale.
