Hi @JoeSheppard,

There's no charge to unlock your UK call, text, and data allowances when travelling to the Republic of Ireland, and there's no fair use limit when using data in the Republic of Ireland. This applies to all plans. The link @MZone provided can give you more info about this, and the rates for all plans and destination.

Thanks,
Jonathan
