As a tourist, I had some concerns about getting a SIM card while traveling in Ireland but was able to get it taken care of without hassle at the 3 store. The staff was lightning quick to serve customers compared to American cellular stores and quite a bit more knowledgeable as well. For exactly a 20 Euro note, I was set up with unlimited data over 4g pretty much everywhere I went in Dublin, calling and texting to in network numbers, and some credit toward other calls if needed which I didn't use. It even worked with fast 3g data in Northern Ireland though I had to enable data roaming for some reason. The connection was very fast and I often tracked up to 20 mbps across the city. They even helped verify settings on my phone for me. Great plan for travelers who need connectivity. read more
