In this guide you will find all the info you need for buying a local sim card: where to buy a sim card, best 4G/5G network, up to date prices as per June 2022, my recommendation and even information about international sim cards and e-sim cards for Ireland.

Buying a local prepaid sim card is the first thing I do when arriving to a new country and as I am trying to visit every country in the world you can find more than 200 prepaid sim card guides on Traveltomtom: Europe, USA, Canada, MexicoRome, Guatemala, Zambia, Dubai, Jordan, Vietnam, every country and capital city in Europe and many more.

Why buying a sim card in Ireland

First of all to save on high roaming costs! Overseas data plans are expensive and even worst they limit data speed. With a local prepaid sim card you get the best 4G/5G connection and the fastest internet speed.

When you are staying in Dublin then big chance your hotel or accommodations has free WiFi and so do most bars and restaurants. But do you want to rely on other people? Having a data connection on your phone makes traveling so much easier. Ordering a taxi through an app or getting directions from Google Maps, finding nearby places of interest, emergencies, etc.

Also keep in mind that public WiFi is through an unsecured connection, the use of a VPN in these cases is recommended.

My recommendation

Traveltomtom recommends a Three or a Vodafone prepaid sim card for Ireland. In fact there is not much difference. Prices and 4G/5G network are more or less the same. For €20 you get unlimited data for a month. Pretty good, right?

We also recommend looking into travel sim cards for your trip abroad. These sim cards you can order online and get shipped to your home address. Have a look at my comparison of the best international sim cards in 2022 and find the one that suits your trip to Europe. For $29.90 USD you can already get 10 GB data. Even easier?
