Our verdict

Three Ireland suits people who already own a handset and want generous data without paying for a phone, with plans starting at €14 a month and All You Can Eat allowances. The catch is commitment: the opening rate belongs to the longer contract and prices step up each April.

Pros and cons

Pros

  • Every listed plan, including Three SIM Core and Three SIM Freedom, comes with All You Can Eat data, so the allowance is not what limits you.
  • The entry price of €14 matches the unlimited price of €14, so you do not pay extra to stop counting data.
  • Contract lengths run 1, 12 and 24 months, so a shorter commitment sits alongside the longer ones.
  • An eSIM is available and wifi calling works, so a compatible handset can be set up and used indoors without fuss.

Cons

  • Prices step up each April under Annual price increase of EUR 2.50 in April each year, so the opening figure is not the figure you keep for long.
  • Data rollover is not offered, so unused data does not carry from one billing period into the next.
  • EU roaming applies on fair use terms rather than being included outright, so heavy roaming use can cost extra.
  • The €14 entry rate belongs to the longer commitment, so the lowest line is also the one that ties you in longest.

Who it suits

  • People who already hold a compatible handset and only need a SIM to put in it.
  • Data users who would rather not count gigabytes each month.
  • Anyone comfortable tying a line to a contract, since the lowest rate comes with the longest term.

Who should look elsewhere

  • Anyone hoping to start at no cost, because yesss! lists a price from €0.
  • Readers who want prepaid billing to be the whole deal, since GETESA sells on prepaid and contract while the €14 rate here runs on the longest commitment.

Plans and prices

Three Ireland sells SIM only lines on its own network, and the two numbers that matter sit closer together than you might expect. Plans start at €14 a month, and the unlimited data option costs €14. Because those figures match, you are not paying a premium to stop counting your data. Two names do most of the work. Three SIM Core runs on All You Can Eat data with a fixed monthly fee, while Three SIM Freedom opens at €14 for an introductory period before moving to a higher standing rate under the same plan name. The standing rate is the figure to budget from, not the opening one. Read every price next to its plan name, because the entry rate belongs to Three SIM Freedom, which also carries the longer commitment, while Three SIM Core sits above €14 with its own term. Both plans include All You Can Eat data, so the real choice is length and total cost, not allowances.

How it compares on our data

On entry price, Three Ireland ranks 207 of 258 brands. That places it in the middle of the field, and cheaper SIM only entry points do exist among the sellers that sit lower in the ranking. The unlimited price tells a different story. Three Ireland ranks 42 of 173 on what you pay for unlimited data, a far stronger position than the entry ranking alone would suggest. Put the two together and the shape is clear: €14 is not the sharpest opening figure around, but €14 for unlimited data sits well inside the stronger end of the field. So if the starting number made you pause, the unlimited ranking is the more useful one to weigh before you decide.

The company behind it

The provider is Three Ireland (Hutchison) Limited, the legal entity standing behind the Three Ireland brand in Ireland. You are dealing with the network itself rather than a broker or a virtual operator, so the company that sets the terms is the one that carries the billing. Help runs on email, chat and phone, so there is a phone route as well as written and community routes. That mix suits anyone who would rather settle a bill query on a call than through a form, and it equally suits anyone who prefers to keep the same conversation in writing. Because Three Ireland (Hutchison) Limited is one named company rather than a marketplace of resellers, a dispute has a single addressee, and the same firm handles both the query and the contract behind it.

How Three Ireland compares

Frequently asked questions

What does a SIM only plan from Three Ireland cost?+

Plans start at €14 a month, and the unlimited data option sits at €14. Both named plans, Three SIM Core and Three SIM Freedom, carry All You Can Eat data. Because the line is SIM only, you bring your own handset, so no handset cost sits inside the monthly figure.

Is the starting price the price you keep?+

Not always. Three SIM Freedom opens at €14 for an introductory period and then moves to a higher standing rate, so budget from the standing figure rather than the headline. Separately, Three Ireland applies Annual price increase of EUR 2.50 in April each year, which lifts the monthly cost again each April.

How long are the contracts?+

Contract lengths run 1, 12 and 24 months, so both a short monthly style term and longer commitments exist. Billing is not contract only: Three Ireland also offers contract, rolling and prepaid. The lowest entry price sits on the longer term, so the cheapest line is also the one that ties you in for longest.

Can I get an eSIM and call over wifi?+

Yes on both counts. An eSIM is available, so a compatible handset can be set up without waiting for a physical SIM, and wifi calling is supported for calls over a fixed connection. If you need a hand setting either up, support runs on email, chat and phone.

What happens to data I do not use?+

Data rollover is not offered, so whatever you leave unspent in a month is gone by the next billing date. Heavy users should treat the allowance as a monthly ceiling rather than something to bank. If you travel, roaming in the EU applies on fair use terms rather than as unlimited extra data.

Can I roam in the EU?+

EU roaming is offered on fair use terms, which means a usage condition rather than unlimited included data. Frequent travel therefore is not simply free extra, so read the fair use condition before you commit to a contract. You can ask about the detail through email, chat and phone.

Who am I actually dealing with?+

The provider is Three Ireland (Hutchison) Limited, the legal entity behind the Three Ireland brand. It is a network rather than a broker or a reseller, so the company that sets the terms is the company that issues the bill. Support on email, chat and phone sits with the same company.

How does this compare with other sellers?+

On entry price Three Ireland ranks 207 of 258 brands, so the opening figure is mid field. On the unlimited price it ranks 42 of 173, which is far stronger. yesss! lists a price from €0, below anything here.
