Can I use my phone in Ireland?
Yes, your US and UK phones will work in Ireland. However, your options are limited if you have a carrier-locked phone or one that doesn’t support local frequency bands.
Ireland uses 24 frequency bands, including GSM networks, meaning most phones can easily access mobile internet. But checking if your phone is carrier-unlocked will give you more options, like using an eSIM or a local SIM. If it’s carrier-locked, you’ll be restricted to roaming.
Here’s what you should consider based on your local carrier.
Home country | Carriers | Will my phone work in Ireland? |
USA | T-Mobile, AT&T, Verizon | Yes, but check if your phone is carrier-unlocked or you’ll be limited to international roaming. |
UK | Vodafone UK, O2, Three, EE | Yes, all phones sold in the UK after 2021 are carrier-unlocked. |
How to use your cell phone in Ireland
Using your cell phone in Ireland is possible, and you have four different options to get mobile internet during your trip.
Let’s explore your different options to stay connected in Ireland and how they work.
eSIM for Ireland
Having an eSIM-compatible phone means you can use an eSIM to get mobile internet in Ireland faster and easier.
The best option is to use the Holafly eSIM for Ireland. You’ll get unlimited mobile data for 1 to 90 days, and depending on your trip length, pricing can be as low as $1.55/day.
Plus, you get up to 500 MB of hotspot data per day, 24/7 customer support, 5G data speeds, and you can activate your eSIM within minutes.
Roaming in Ireland
Roaming in Ireland will vary based on where you’re traveling from.
Despite Ireland being in the EU, roaming is typically free of charge for UK visitors. Vodafone UK, O2, EE, and Three all include Ireland as a roaming-free destination, as long as roaming is included in your monthly or pay-as-you-go plan. This means you can access your home allowance at no extra cost.
For US users, data roaming is free only on selected plans. For example, with T-Mobile, you get up to 15 GB of high-speed data and unlimited data at 256 kbps as part of Experience Beyond and Experience More plans.
If you’re not on an eligible roaming-free plan, data bundles with up to 30 days and 15 GB of mobile data are available. These bundles range from $5 to $50.
For Verizon and AT&T, you can rely on their international roaming pass, which costs $12 per day and includes unlimited data, phone calls, and texts.
Physical Irish SIM card
If you have a SIM-only phone, you can use an Ireland SIM card from Eir, Three, or Vodafone.
Here’s a quick breakdown of what each carrier offers with their local SIM cards:
- Eir Ireland: Offers tourists two prepaid SIM card plans. Prices range from €10 (~$11) to €20 (~$21).
- Three Ireland: Offers three prepaid SIM card plans, Super Surfer, Total Talker, and Connect Complete, which work for up to 38 days. Pricing ranges from €20 (~$21) to €30 (~$31).
- Vodafone Ireland: Offers different prepaid plans ranging from €20 (~$21) to €30 (~$31).
Pocket WiFi for Ireland
Traveling to Ireland in a large group? Or need super high-performing internet for remote work? A pocket WiFi device is a popular choice.
Plans range from $7 to $15.95 to $15 per day with Travel WiFi, while Hippocket WiFi charges €6.95 to €8.95 (~$8.10 to $10.43) per day.
Both companies offer limited and unlimited data plans, and you have to include delivery fees and any additional add-ons you include, like portable charges.
But there’s a cheaper alternative: the Holafly Plans eSIM subscription.
For $64.90/month, you get unlimited data, unlimited hotspot data, up to 5G data speeds, 24/7 customer support, a European phone number, and coverage in over 170 destinations.
That’s global coverage and peace of mind as you travel, all for less than the price of a coffee a day.
