We loved using Wifi Candy. We didn't have to mess with changing data plans, SIMS cards, or any of that. We left our phones in airplane mode and used the Wifi Candy for everything. It took us across the country from Dublin, to Killarney, to Galway and back. Not once did it lose service. We used it to navigate on our map app across the entire country. We could call, text, and Facetime as usual using it. It was easy to pick up and drop off. Highly recommend.
