Three is a global telecoms brand which has a presence in 11 countries around the world. It launched in the UK back in 2003 and has been growing its network capabilities ever since. It is one of the UK’s 4 main mobile network operators and is steadily rolling out its 5G network across the country. The firm is owned by the multinational conglomerate CK Hutchison, which has interests in ports, energy, retail and infrastructure, aside from its telecoms businesses.

Three offers pay-monthly handset contracts on 24-month commitments, SIM-only plans on rolling monthly, 12-month or 24-month contracts, and pay-as-you-go plans. The network operator also sells competitively-priced home broadband packages which use mobile data to get households online.

Three’s mobile services have a particularly good reputation when it comes to international roaming, allowing customers to use their calling, text and data allowances in a large number of countries at no extra cost.

Three customer reviews

Regulator Ofcom carries out a survey of mobile network customers every year to gauge their satisfaction with their provider. In 2020, for which full data is available, only 86% of Three customers told Ofcom that they were satisfied with the overall service they received, the lowest score among large mobile providers last year.

However, the same survey found that 88% of Three customers questioned felt they received value for money from their carrier, the third best score on this measure among larger providers over the same period.

But this response isn’t matched by customers using the reviews site Trustpilot, where the firm gets a very poor overall customer score of 1.6 stars out of 5, based on over 19,400 reviews posted. Just over half of reviewers (53%) rated Three “Bad”, the worst rating available. Meanwhile, only 31% of respondents said Three provided “excellent” service (last updated October 2021).

Pros and cons of Three


  • Large selection of plans. Three offers a wide range of call and data plans, and can offer decent packages for customers who want large amounts of data.
  • Decent international roaming option. Three’s pay monthly, SIM-only and PAYG customers can all use their allowances in a large range of countries at no extra cost.


  • Poor customer service scores. Three isn’t highly rated for the quality of its customer service.

Our verdict: Is Three any good?

Three offers wide 4G coverage across the UK, alongside its steady roll out of 5G. It offers a wide range of plans, and can represent decent value for money, particularly for those looking for SIM-only contracts.

Sadly, it lags behind some of its competitors when it comes to the quality of its customer service. But if you’re looking for competitively-priced call and data plans with strong international roaming options, Three may offer what you need.Ready to compare mobile plans?

      Hi Dr nat,

      Thanks for getting in touch with finder. I hope all is well with you. :)

      Yes, you can use your mobile plan in London and Florida, USA. Upon checking, you can take advantage of Three Mobile’s Data Passport. You can pay £5 a day and you will enjoy unlimited unrestricted data. Moreover, you can also use Three Mobile’s Go Roam which allows you to use your SIM with no extra cost as long as you use it in one of the countries covered by the promo.

      I hope this helps. Should you have further questions, please don’t hesitate to reach us out again.

      Have a wonderful day!

    Is there a Company that covers my phone for largely emergency use. I like the comfort of having a mobile I know I can use when travelling on a Motorway and not much else, maybe the very occasional short call. I dislike the one’s that you pay for per month and if you don’t use it then it’s gone! Perhaps should add I am 71 and find myself driving less and less too.

      Hi Patricia,

      Thanks for getting in touch with finder. I hope all is well with you. :)

      Generally, if you will subscribe to a prepaid promo, the expiration of your credit will shorten. However, if you want to keep it longer than usual, you may want to top up your phone with regular load or credit. This way, your credit will stay with you longer.

      Unfortunately, it is difficult to find a company that allows you to carry credit without any expiration. So, you just have to choose between topping up with a regular load, which have a longer expiration date or simply subscribing to a prepaid promo, which comes with more perks though it expires faster.

      I hope this helps. Should you have further questions, please don’t hesitate to reach us out again.

      Have a wonderful day!

    I am journeying to the UK for approximately 12 months and would like to know what you would suggest for a sim card. I won’t be making a lot of calls, so it is mainly data for photos etc.

      Hi Jeffrey,

      Thanks for visiting finder!

      Depending on how heavy are you on calls and data, you may compare Three Mobile’s roaming features such as Feel At Home and Data Passport which allow you to use your plan overseas. Alternatively, you may also check local sims in Indonesia and see if their rates are cheaper than your provider’s roaming charges.

      Feel free to message us if you have other questions.

      Best regards,
