For our August trip I am thinking of purchasing a mobile wifi hotspot ahead of time and buying a data only sim card once we arrive. We are landing at Shannon and then driving towards the Cliffs of Moher. Our trip is only for 9 days but we'll have eight people total, so we might go through a lot of data.
Does anyone have a suggestion on a good place to buy a sim card that will work well near Shannon or along our way? It would need to work all over the Republic of Ireland.
Thanks in advance for any replies.
