Three UK Reviews 

Great Service

Really friendly staff, sorted very quickly.

Great service in the Barnstaple store. Very friendly and professional. Leah and Aidan helped me with my contract.

I do not recommend any services provided by this mobile network.
They probably have the worst signal coverage out of all available networks in the United Kingdom.It is simply shameful that in 2026, with such advanced technology, Three customers still do not have internet access in places where it is most needed.Yesterday, just to log into my bank account and check my balance, I had to walk outside the shop to do it, even though my phone showed four bars of signal and a 4G network.Even near my own home, in the city, there are many places where I have no internet access at all.This matter will definitely end up in court, so you can save my comment and my opinion, because there are only two options: either I sue you, or you sue me — the choice is yours.I am eagerly waiting to meet you in court, and we will see what you say then and how you explain the fact that customers who pay their bills have no internet access at every step

Great experience. The staff was very helpful! Especially Jack

team were very helpful in my roaming questions

The staff were all super helpful and knowledgeable. Jack greeted me when i arrived, helped me find what i was looking for and introduced me to an associate who put my sale through quickly and with a smile. Very satisfied with my experience!

Waste of money and time....sooo much time....dont call customer services unless you have a 30 mins to an hour. Even something that should be simple, like paying a month device payment and setting up new bank details....42 minutes. It makes you want to hear the hold music for a break from the robotic customer advisors.
I have paid off contracts and cannot wait to pay off device agreements so i never have to deal with 3 network again.

Dear Three Customer Service Team,

Account number: 110487462
Contact telephone number: 07455377443

I am extremely disappointed with the way you have handled my account and my repeated attempts to contact your company.

I made a payment of £47.99 by card through your app on 14 October 2026. However, after making this payment, my account is still showing an outstanding balance of £46.

I do not agree to pay this remaining £46 because I have already paid the amount of £47.99 that I was told was due. You have charged me £94 for this month, and I request that you review my account, correct the balance, and remove the disputed £46 if it has been charged incorrectly.

I have repeatedly tried to contact your company by email and through your app, but I have received no response. I have explained my situation several times, yet my messages appear to be ignored. This is unacceptable.

I also contacted one of your employees approximately one month ago regarding the return of my internet router. She told me that I would receive a letter at my home address on 7 October 2026, containing instructions on how to return the router. However, I have not received this letter or any further response from your company.

I have also tried to contact you privately through your app, but nobody has responded to my messages. I have made every effort to resolve these matters directly with Three, but I have received no help or response. I now have no choice but to raise my complaint through social media.

I have cancelled my Direct Debit permanently and will not use Direct Debit again.

Please review my account, explain why the remaining £46 is still showing after my payment, correct any incorrect charges, and send me the promised router return instructions as soon as possible.

Please treat this message as a formal complaint and provide a written response addressing all these issues without further delay.

Finally, once my current contracts have ended, I will not renew them or enter into any further contracts with Three. This will be my last contract with your company.

I expect this matter to be taken seriously and resolved as soon as possible.

Kind regards,

Basil Al Jassim

Friendly, efficient, able to cater for my needs quickly.

Really helpful and went over all the options for us

We have very good experience with guy named ‘Kai’ was very helpful

Amazing experience with Mr Abraham

She is the best worker I have ever met. She is so natural in her job. Chardonnay really took away all the stress of buy and changing over from the old phone to the new one. I couldn't have done it without her help.

Amber very helpful and knowledgeable and friendly

Great interaction, great service Amber

⭐⭐⭐⭐⭐ Absolutely Outstanding Service from Saira at Three in the Cardiff branch!

I honestly cannot praise Saira enough. From the moment I dealt with her, she was absolutely phenomenal. Her professionalism, kindness, patience and genuine willingness to help were on another level entirely. She went above and beyond what I could ever have expected, making the entire experience an absolute pleasure from start to finish.

Saira is a true credit to Three. She made me feel valued as a customer, listened carefully to everything I had to say, and approached everything with such a positive attitude and a genuine desire to help. Her knowledge, attention to detail and exceptional customer service were second to none. It is incredibly rare to come across someone who takes so much pride in their work and makes such a lasting impression.

What really stood out was her attitude. She was friendly, approachable, patient and incredibly professional throughout. Nothing felt like too much trouble for her, and she made sure I felt supported every step of the way. She didn’t just do her job; she went the extra mile and made the whole experience genuinely memorable.

If every company had a Saira, customer service everywhere would be on another level! Employees like her are the reason customers remain loyal to a business. Three should be incredibly proud to have someone like her representing their brand, and I genuinely hope her hard work and dedication are recognised by management.

Saira, thank you so much for your outstanding service. You are an absolute star, and you deserve every bit of praise coming your way. If I could give you 10 stars out of 5, I absolutely would! 🌟🌟🌟🌟🌟

An absolute credit to Three. Exceptional service, exceptional attitude, and an exceptional person. Thank you, Saira!

Veryy helpful! Thank you Samella :)

Excellent service and advice. The sales advisor went out of their way to give various options for an upgrade to my iPhone. The process for the upgrade was seamless and the deal value for money. I would recommend the branch for outstanding service.

Amber was outstanding, gave optionsnand provided an great advice.
Thanks
