About Three Ireland

Three Ireland launched in July 2005 and at the time was the fourth mobile operator to grace our shores. Initial offerings included postpaid (billed services), but in 2006, Pay-as-you-go (PAYG) mobile services became available. This was followed in 2010 by an innovative prepaid mobile broadband product where vouchers could be purchased and were good for connectivity from one day up to a month.

In 2013, Three Ireland’s parent company, CK Hutchison Holdings, made a play for another Irish mobile operator, O2. By 2015, it fully integrated the O2 brand into Three Ireland.

Is Three an Irish company?

Three Ireland belongs to the CK Hutchison Holdings, which deals with energy, infrastructure, ports, retail, and telecommunication services worldwide. The conglomerate has over 300,000 employees in 50 countries and operates Three Ireland under the umbrella of that global brand.

Three Mobile Deals

a smartphone

As with most mobile providers in Ireland, Three Ireland offers both prepaid and postpaid mobile phone plans. You will either be on the 3G, 4G, or 5G network, depending on the geographical area you find yourself in when using the service.

To simplify the Mobile Phone Service Offers with Three Ireland, we divide them into three common categories:

  • 3 Bill Pay Mobile Plans
  • 3 Prepay Mobile Plans
  • How to top up three?

Three Bill Pay Mobile Plans

3 bill pay customers will first need to decide between a 4G plan or upgrade to a 5G plan.

Those who opt for a 5G mobile plan can pick between prices ranging from €25 to €85 a month. The difference between each plan depends on how much data inside the EU you would like to include, the number of minutes, and how much texting you want to have.

In contrast, 4G mobile plan prices range from €20 to €80 a month.

All Three Bill Pay Mobile Plans come with unlimited “All You Can Eat” data within the Republic of Ireland. Most plans are for a minimum 24-month term, and only a few are for just 12 months.

Three Prepay Mobile Plans

Pay as you go customers are required to top up every 28 days to maintain their plan active.

Prices start as low as €15 to €30 per 28-day cycle.

You can choose how many features you want to include to select the prepay mobile plan that best suits your needs.

The major difference with prepay mobile plans is you can opt-out or simply stop at any time without any penalties.

How to top up three?

You have the following options to top up Three mobile plans:

  • Three Top Up Options
  • Scheduled Top-up
  • Instant Top-up
  • In-Store
  • From your phone

We examine in detail the various Three top up options below.

Scheduled Top-up

The scheduled top-up with Three Ireland automatically adds credit to your prepay mobile phone when your credit runs low. You can also set up an automatic top-up on a set date of each month.

To activate this Three mobile top-up option, you will first need to register and log in for a My3 account.

Instant Top-up

You can also complete a Three instant top-up with your debit or credit card in the following ways:

  1. Top up online: Head to the Three top-up online webpage and enter the amount and card details to top up your mobile phone accordingly. This option also accepts payments via Paypal.
  2. By SMS: Just text the words 'TOPUP', the amount you would like to top up, and the last four numbers of your registered card. Text to 50100 and you are done!
  3. My3 App: Use your My Three login account to top up. You can also top up for family or friends from the My3 App.
  4. Contact Three Customer Care: Existing Three mobile customers can simply dial 1744 to reach Three Ireland and top up. This is a free call.


You can also visit any 3Store to complete your top-up. You can easily locate the nearest 3Store to you via the suppliers' store locator tool.

From your phone

You can contact the Three Customer Care Team by dialling 1744, this is a free call. If you have other queries about your mobile phone plan, have a look at our list of Three contact numbers to reach the appropriate department according to your enquiry.

Three Broadband Deals

Globe held in hands

Three’s broadband offering is a little different from others on the market in that you can opt for prepaid or postpaid (bill pay) broadband. The options for Home Broadband are:

  1. 3 Broadband Unlimited 5G Fast
  2. 3 Broadband Unlimited 5G Pro
  3. 3 Broadband Unlimited 4G
  4. 4G SIM-Only Broadband
  5. Prepay Broadband

Are Three Broadband Offers unlimited? Although advertised as ‘unlimited’, all Three Broadband deals are limited to 750GB of data per billing cycle. This is considered to be a ‘fair usage’ limit.

Three Broadband Unlimited 5G Fast Plan

To be eligible for this plan, you first need to ensure your home is within the geographical area where Three’s 5G broadband network coverage is available.

Although advertised at a nice even €30 per month, this is the price you pay only for the first 12 months. The plan has a minimum 24-month term and costs €50 per month for that second year and thereafter.

A free router is included, but you will have to do the installation yourself, which can be a little complex if you do not have an antenna already installed.

Three Broadband Unlimited 5G Pro Plan

Once again, this plan is only available for those located inside Three’s 5G broadband network coverage.

The difference between this plan and the 3 Broadband Unlimited 5G Fast Plan is having the installation done by Three Ireland’s professionals.

They again price the first 12 months at €30 per month and €55 per month for the second year of the minimum 24 month term.

There is a one-time €149 fee for the antenna and router installation. Although expensive, you can at least rest assured the installation will be done properly.

Three Broadband Unlimited 4G Plan

If you don’t live within Three Ireland’s 5G network, never fear as their 4G covers 99% of the nation’s territory. Although the plan offers slightly lower speeds than the previous two, its price remains lower.

It is again a 24-month minimum contract with the monthly price remaining at €30 per month for the duration of the contract.

Like the 3 Broadband Unlimited 5G Fast Plan, you will need to complete the installation yourself.

4G SIM-Only Broadband Plan

For those who already own a router or are simply looking to connect an additional device in their home, Three Ireland’s 4G SIM-Only Broadband Plan is a great option.

Depending on how much data you intend to use, you can have a SIM-only plan starting as low as €15.99 or as high as €69.99 per month. Have a look at Three Ireland’s mobile offers below for further details.

Prepay Broadband Plan

The Three prepay broadband plan gives you no-strings-attached broadband for €30 per 28-day period. This type of plan can be ideal if you are moving house, renting an Airbnb, in temporary accommodation, or for your country retreat home and need broadband.

You are limited to a maximum of 30 Gb usage per 28-day period. To prolong your plan, simply make a minimum €30 top-up on your Three top-up account before the end of the 28 days.

If you wish to stop the plan, simply do not make a top-up and the account will automatically cancel itself. It’s that easy!

Other Three Ireland Deals

Regardless of whether you decide to become a Three Ireland mobile or broadband customer, joining either one will give you access to much more. We explore other extras offered exclusively to Three Ireland clients.

3Plus Rewards

We’ve seen some great reward schemes with gas and electricity suppliers before, such as Electric Ireland and Bord Gáis Energy! We are happy to see Three Ireland move into the loyalty scheme arena with its 3Plus reward offers for loyal customers.

All Three customers have access to 3Plus Rewards (also known as Three Plus), whether pay as you go or postpaid. Advantages of belonging to the 3Plus rewards scheme include:

  • Pre-purchase access to 3Arena and 3Olympia theater events
  • Discounts in restaurants, cinema, and shopping
  • 3Plus breaks, great value on weekend getaways

3Money Prepaid Mastercard

Another interesting addition to the Three Ireland range of offerings for customers is the 3Money prepaid Mastercard. Available exclusively to Three mobile or broadband customers, the card can easily be topped up via your bank account or bank transfer and can be used abroad.

The fact that it’s prepaid adds an extra layer of security as if it’s stolen, no massive bills can be run up on your behalf. The card is free and, if lost or stolen, can be replaced with the same amount of credit as the original card.

Three Ireland Business Offers

On top of residential plans, Three Ireland also offers a nice variety of broadband and mobile plans for businesses.

Small business owners can also look at Digiweb, Eir Ireland Imagine Broadband, or Pure Telecom business packages to see which has the best one for your needs. We look at Three Ireland’s business offers below.

Three Business Broadband Plans

Customers looking for broadband solutions for their business can choose from:

  1. 3Business Broadband Express
  2. 3Business Broadband Advanced
  3. Three mobile broadband

Three Business Broadband Express

This introductory broadband package from Three Ireland comes with the 5G capability enabled. This is great if your business is within Three’s 5G broadband network coverage.

Pricing for this broadband plan is €36 per month, excluding VAT. The plan has a minimum 24-month duration, has unlimited data, and comes with a free router. The only downside for this plan is that the installation is not included and you will therefore need to do it yourself.

Three Business Broadband Advanced

This is a very similar broadband offer to the 3Business Broadband Express plan. The crucial difference is having the antenna and router installation completed by a Three Ireland technician.

The price for this option is €44 per month, excluding VAT. The plan has a minimum 24-month duration, has unlimited data and 5G capability enabled.

On top of the slightly higher monthly price, you will also have to pay a one-time €121 device fee.

Three mobile broadband

Since Three Ireland's broadband connections come from wireless tower signals anyway, you may want to consider obtaining a mobile plan for your business's connectivity needs.

The 5G speeds are said to be fast enough to match just about any cable or fibre-optic broadband connection. Why not get a Three mobile data plan to give you the bonus of mobility for your connection needs? Have a look at the various mobile offers for businesses below.

Three Ireland Business Mobile Offers

globe with sim cards as satellites

Three’s business mobile plans vary according to the size of your business. For ease, we have divided the Business Mobile Service Offers into three categories:

  1. SIM-Only Plans
  2. 1-4 employees Plans
  3. 4+ employees Plans

Business customers will also be happy to see the ‘Virtual landline app’ as an available feature on any mobile plan.

Also known as Three Wi-Fi calling, the virtual landline app allows you to make and receive calls like a regular landline phone. Using the Three Wi-Fi calling feature is essential for many businesses and is something that residential customers have been waiting for years now from Three Ireland.

Three Business SIM-Only Plans

All of Three’s mobile SIM-only plans come with ‘All you can eat’ data, unlimited text, and unlimited calls. A fair usage policy applies for these unlimited features.

The SIM-only plan prices range from €14.99 to €40 per month, excluding VAT. The key differences are in how much data and how many international minutes to include with your plan.

Three 1-4 Employees Mobile Plans

Again, we see all Three’s mobile plans come with ‘All you can eat’ data, 5G access, unlimited text, unlimited calls, and the Three Wi-Fi calling feature.

Prices start at €45 and go as high as €80 per month, excluding VAT. There is a lot more variety of plans for businesses with 1-4 employees compared to the business SIM-only plans. One can opt for unlimited UK calls and text, international roaming features, mobile security, and much more.

It is important to have a good understanding of your business needs. For example, how much traveling you expect your employees to do, so you can choose the right plan.

Also note that these plans come with a 24-month contract, double the duration of SIM-only plans.

Three 4+ Employees Mobile Plans

With 4+ employees, businesses will continue to have the ‘All you can eat’ data, 5G access, unlimited text, unlimited calls, and the Three Wi-Fi calling feature.

With more employees using the services, prices drop compared to the 1-4 employees’ mobile plans. With over 4 employees, the Three mobile plan prices range from €30 to €45 per month, excluding VAT.

Again, it is important to know your business needs to choose the right features with these mobile plans. International roaming, unlimited UK calls, and text, mobile security, are just a few of the mobile features available on these plans.

What is fair usage? The Fair use policy is a policy that the EU has set to limit abuse from users about these ‘unlimited’ features. It is set at such an outrageous amount that any ‘regular’ user would never surpass the limit, but low enough that any illegitimate users, such as anyone doing spam or things along these lines, would be capped and caught.

Other Three Ireland Business Solutions

Three offers businesses more than just broadband and mobile solutions. Here are a few of the other services you can get from the company.

Managed connectivity

With Three’s managed connectivity option, you have the option of Three providing high speed and secure solutions for WAN, LAN, internet access, Wi-Fi, firewalls, and server colocation services.

Managed mobility

Three’s managed mobility options for business comprise mobile device management, mobile application management, mobile content management and mobile data management, and security. These options enhance security features, with options such as encryption and secure file syncing, which are crucial for many businesses’ operations.

This managed feature from Three Ireland includes options such as:

  • Mobile call recording
  • Hosted UC
  • Cloud-based telephone solutions

Last but not least, Three brings businesses into the future with the Internet of Things (IoT). This level of connectivity can boost security, customer engagement, and even energy saving through smart energy grids.

What is My3?

My3 is the Three login online account for both mobile and broadband users, prepaid or postpaid. Three Ireland customers can pay bills, check upgrade eligibility, verify their account balance, and much more from their Three login online account.

Customers with prepaid plans can top up, check their credit balance and buy add-ons, such as extra data from their My three login account. From My3, customers will also be able to send free web texts.

Customers who have registered for the My three login account can also download the My3 app and complete all the same functions you would from your Three online account. Unfortunately, the My3 app isn’t well-rated in Ireland with 2.6 out of 5 stars in Google Play and 1.2 out of 5 stars in the Apple store.

Three Ireland Reviews

Three Ireland has over 700 reviews on and a rating of 1.4 out of 5 stars. Unfortunately for Three, 93% of all reviews are classed as poor or bad. This says a lot about what customers think of the provider.

Customers who were unhappy with Three cited issues with the service received and with the internet not working.

Customers who were happy with their Three Ireland experiences spoke about excellent customer care and how happy they were with their plan.

No internet or service for weeks and I live in town. When I complained to customer care they said the can’t give a timeframe of when things will be normal again, while continuing to charge me money but leaving me unable to make a phone call. I will switch to a different network today as this is ridiculous. Agata Gondek, Trustpilot reviews.

It is worth stating that more customers take the time to write a comment on review sites when they have a complaint or problem rather than when they are happy. That said, a 1.4 overall review score is quite low and is worth keeping in mind if considering using this broadband and mobile provider.
