Tips for Using Your Mobile Phone in Ireland
Our mobile phones are ‘command central'. It is your main mode of communication, the camera you use most often, your calendar, and your filing cabinet. So when you travel you want to use it just like you do at home.
There's only one problem – the cost.
It's not always cheap to use your cell phone in Ireland – but with the proper planning you won't be surprised with a nasty sticker shock on your next bill.

Tips for Using Your Mobile Phone in Ireland
Roaming and data charges in Ireland can break your budget if you're not careful. These tips will keep you connected affordably.
- Contact your cellular provider and inquire about using your mobile phone in Ireland. Confirm that your device is compatible with GSM (Global System for Mobile) used in Europe, and then inquire about an International calling plan which includes both talk minutes and data. Most cellular providers offer a ‘use it like you do at home' option for an additional cost per day. (More on this below.)
TIP: My personal advice on these plans is for one person to use this if a home phone number or text is needed during your trip. Daily costs can add up quickly so supplement others in the group with an eSIM or portable wifi device. - Purchase an eSIM or Irish SIM card. If your phone is able, an eSIM is the easiest option. A quick scan of a code, a simple toggle of settings, and you are ready to go! My go-to eSIM provider is Wifi Candy. Easy to set up and great connectivity.
A replaceable SIM card- which you put into your phone, removing your local SIM- only works if your phone is unlocked (US phones under contract usually aren't- ask your service provider if yours is unlocked or can be). You can pick up a prepaid SIM card in Ireland at the WH Smith Shop at Dublin or Shannon Airpots, the Left Luggage store in Dublin airport, or at any Tesco, Three, eirMobile, or Vodafone retailers. Learn more about SIM cards here. - Rent a mobile wifi unit. Most car rental companies now offer the option of adding a mobile wifi unit to your rental. Their rates, however, are high. For mobile wifi in Ireland I recommend Wifi Candy. Their prices are affordable, and data is unlimited for the duration of your rental. Just set your phone to ‘wifi calling' to make phone calls or use a calling app (below).
- Obtain a prepaid phone when you arrive. It's just handy to have a phone – you may need to make quick calls to B&Bs for directions or to make reservations for dinner or a tour you just found out about. If you don't need a ‘smart phone', you can rent CallCandy from WifiCandy which offers unlimited calling in Ireland, the EU & the UK or pick up a disposable prepaid phone at Tesco locations throughout Ireland.
- Use free wifi and connect with Skype, Facetime, WhatsApp, or Google Voice. You'll find free wifi all over Ireland – in your B&B or hotel, many restaurants, and even stores offer connectivity. Keep your wifi turned on and set to notify you when it is available.
Don't forget to turn your data off or keep your phone in airplane mode to avoid international roaming fees!

Mobile Phone ‘Use It Like You Do at Home' Plans Add Up
There is no doubt that being able to use your mobile phone in Ireland like you do at home is incredibly handy! But is it the best option for you?
Verizon coverage in Ireland: Verizon's Travel Pass is $12 per day used. You could also upgrade to the International Monthly Plan for $100/ month.
AT&T service in Ireland: AT&T has International Day Pass for $12 per day and ‘pay as you go' international rates.
Using T-Mobile in Ireland: T-Mobile offers International Passes in 1, 10, and 30 day bundles with unlimited calls but limited data. T-Mobile's Go5G plans are also international plans that include 5GB high speed data, unlimited basic data & text and $0.25/ min calling.
If you are in Ireland for 8 days, these international plans will cost $96, if you use the phone daily. Charges only accrue when you use your phone.
But, that deal is only for your phone.
If everyone in your group has a phone the $12 per day per person adds up quickly!
For approximately the same cost you can rent a personal wifi unit from Wifi Candy and connect 10 devices to it- phones, tablets, laptops, even cameras!
Bonus: WifiCandy offers connectivity throughout the UK and Europe, so when your travels take you out of Ireland you'll stay connected!
Choosing the Right Connectivity Plan for Your Trip
When you're traveling solo it's easy to choose an international calling plan from your cellular provider or a SIM/eSIM and be set. But when you are traveling with multiple people the choice may be less clear.
It's important to know how you plan to use your mobile phone while traveling to determine the best option for you and your family or group.
If you know you need access to receive phone calls and texts to your ‘home' phone number, you will definitely want an international plan from your mobile provider. But, when traveling with family, not everyone should need that level of connectivity.
If you want the ability to make calls but don't need your phone number, an eSIM may be the right option for you if your phone and the eSIM support Wi-Fi calling. Be sure to check the eSIM information before purchase. eSIM are available with multiple data options. Average data use is 5GB per month, which is more than enough to run maps on a 10-day self-drive trip.
For a family or group of people who only need data, a portable Wi-Fi device is an easy, affordable option that can connect up to 10 devices at one time.
Don't forget about security! Remember that free Wi-Fi is not secure so if you plan to do anything that could involve banking or money (even logging into your credit cards), a secure network or VPN is recommended.
Tips for Making the Data Last
Using limited data on your mobile phone?
- Decide what apps you really need- and then turn off or remove all the others.
- Turn off instant notifications and app syncing.
- Turn off the data or use your phone in airplane mode. Only turn off airplane mode to make calls and turn on data when needed.
- Sync email, check social accounts and reply to messages over a wi-fi network.
- Use a data usage counter like My Data Manager (available from iTunes or the Play Store) to monitor your usage.
- Don't forget: if you go over your data limit, you are charged at the international roaming rates in your contract (so watch those numbers!)
