Three Ireland: What do they have to offer?

Three logo

Three, officially known as Three Ireland, is a well-known operator, with a reported 35% market share of mobile customers in early 2019. Three are also set to roll out WiFi calling in 2020, enabling customers to make free calls via WiFi to other connected users.

A short history of Three

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

Three in Ireland

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

In 2013 Three’s parent company CK Hutchinson then made a play for another Irish mobile operator, O2, and the brand was fully integrated into Three by 2015.

Three’s market offering: is it any good?

With plenty of broadband and mobile offerings as well as enticing extras such as unlimited data, Three’s broadband and mobile offerings definitely hit the spot. While the range offered isn’t as complete as other providers who also offer their own TV packages, all that data definitely means you shouldn’t have any issues streaming your Amazon or Netflix favourites.

Three broadband offers

Three’s broadband offering is a little different to others on the market in that you can opt for prepaid or postpaid (bill pay) broadband.

Three prepay broadband

Moving house, renting an Airbnb, in temporary accommodation or away at a country retreat and need broadband? With Three’s prepay broadband plan you can have no-strings broadband from €5 a day. Admittedly much more expensive than Three’s bill-pay broadband plans, this is still a useful option for when you’re stuck. Essentially, it’s the same as mobile broadband.

Three bill-pay broadband

Three’s bill-pay broadband options have no connection fees and can include unlimited data from just €30 a month.

Three mobile offers

As with most mobile providers in Ireland, Three offers both prepaid and postpaid mobile phone plans. Pay as you go customers can benefit from Three’s “All you can eat” data offer whereby if you top up by at least €20 every 28 days, you can get free data within the Republic of Ireland, unlimited texts to Republic of Ireland and EU mobile numbers, free and unlimited Three to Three phone calls, and 8GB of EU roaming data.

Three also have a range of handsets on special offer for Three prepaid mobile customers, but if you prefer, you can, of course, opt for a SIM-only deal.

Bill-pay customers can pick from three plans ranging from €30 to €60 a month, all with unlimited “All You Can Eat” data, as well as benefiting from some serious discounts if they’re in the market for a new handset, with some handsets completely free of cost with certain contracts.

3Plus rewards

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

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

  • Access to competitions
  • Offers
  • Discounts on restaurants, cinema and shopping

3Money Prepaid Mastercard

Another interesting addition to the Three range of offerings for customers is the 3Money prepaid Mastercard. Available exclusively to Three 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. In addition, the card is free and if lost or stolen can be replaced with the same amount of credit as the original card.

What is My3?

My3 is the Three login online account for both mobile and broadband users, prepaid or postpaid. Postpaid and broadband customers can expect to be able to pay bills, check upgrade eligibility for handsets, verify their account balance and view at a glance how many minutes of data or texts they have left.

Customers with prepaid mobile options will be able to tup up, check their credit balance and buy add-ons such as extra data if they have used up their internet data. My3 also has interesting additional benefits such as being able to send free web texts.

Customers who have registered for My3 will also be able to get all the functionality of the online login via the My3 app which comes well rated with 3.5 out of 5 stars on Google Play and 4.4 out of 5 on the Apple app store.
