Very poor network coverage and even worse customer service.
Can't wait for contract to end.

Very very bad service. I’ve contract unlimit internet for £20. But every months take more more money from my account. I’ve called to customer service. Still take more money. Very terrible.

I am 70 years old. Whilst on holiday in rural France I bought a bought a 14 day Go Roam Euro pass and an e-SIM following the instructions and details on the Three App. The next day my phone did not work because (as I found out later during the website Chat session) because your SIM had been turned off as soon as I ordered the e-SIM. However, without a SIM you can not access the security text messages needed to log onto the App , or account, or to activate the e-SIM. No where did it say any of this. Neither were there any warnings given of this at the time of ordering. It also does not make any sense to turn off the old SIM before the new one is activated. I was also told that my old SIM could not be reactivated, which , again, makes no sense, as is all software controlled and that software allows you to activate new SIMS. So I am now paying for a service that I can not use, a 14 day pass that I can not use either and have no phone. All of which is down to Three’s inadequate systems/processes and no fault of mine. Three support and services are useless. AVOID!!

Terrible signal all over the country. Shocking customer service to match.
If I could rate this 0 stars, I would!

I have had one of the worst customer service experiences ever with Three. My iPhone 16 Pro Max was wrongly blocked after I lost my SIM card while on holiday. When I came back and requested a replacement SIM, the automated system also blocked my phone.

Since then, I have done everything possible to prove that the phone is mine. My husband purchased it from Costco Chester on 25/11/2024. I first showed Three the replacement receipt Costco gave me, but they rejected it because it didn’t include the IMEI number. Later, I even found the original Costco receipt, but Costco does not print IMEI numbers on their receipts at all, so Three still refused it. On top of that, I even offered to provide my credit card bill showing the purchase, but they refused to accept that as well.

Even with all this proof, Three continues to keep my phone blocked. The customer service team have been arrogant, rude, and dismissive throughout the process, showing no real willingness to listen or help resolve the situation.

Because of this, I have been left without a working phone for weeks. I cannot even take it to Apple for repair because the device is still blocked. The whole situation has caused enormous stress and inconvenience, and I feel completely let down as a paying customer.

If Three requires proof of purchase with IMEI, then they should check receipts properly before approving SIM-only contracts — not punish customers afterwards by blocking their phones unfairly.

Three should be ashamed of the way they treat loyal customers. Based on this experience, I would strongly advise anyone to think twice before joining Three.

Took 76 minutes to upgrade an existing contract. Unbelievably slow and painful service. Will not renew again.

Dear Three UK Complaints Team,

I am writing to raise a formal complaint regarding the unlawful and unfair charges that I have been subjected to after my contract with Three ended in April 2025.

Despite my contract ending, I am still being charged £78 for a device that has already been fully paid off. On top of this, I have now received a threatening letter regarding debt collection—this was the first communication I received on the matter, which has caused me extreme distress.

I attempted to resolve this via your web chat service, but I was repeatedly passed around without any resolution. Eventually, I spoke to a member of your cancellations team who informed me that my contract is “still roaming” because I supposedly did not call to cancel.

However, in March 2025, prior to my contract ending, a Three agent contacted me to discuss updating my plan and SIM. At no point was I informed that I would continue to be charged if I did not explicitly cancel. If I had been properly advised, I would have cancelled immediately. This failure of clear communication is wholly unacceptable.

To make matters worse, when I attempted to cancel, I was told I cannot do so because I no longer have access to the phone number or the email address registered to the account. I was then informed that I must physically go into a Three store to resolve this—despite the fact that this entire situation is the result of your company’s poor communication and mismanagement.

This has caused me severe stress and upset, and I am now facing unfair charges that I should not be liable for. At the very least, any amount charged after April 2025 should be credited back to my account immediately.

The customer service being in India just doesn’t work. I have been a customer for several years for mobile broadband asked to change to the cheaper contract but they have billed me double for one month and for the old contact the next month. Calling them they give conflicting answers. Still not convinced I’m going to get the overpayment back.

Absolute diabolical customer services...can not wait to buy myself out of this contract and go to a proper mobile provider that will actually help it's customers.

BEYOND TERRIBLE AVOID AT ALL COSTS FOR YOUR WELL-BEING ~ ZERO STARS FOR THIS NASTY DISORGANISATION WHO LIE AS IF IT’S THEIR NATIVE TONGUE JUST TO TRY AND EXHAUST THEIR CUSTOMERS INTO PAYING WHAT THEY DON’T LEGALLY HAVE TO PAY ~ MY HEART GOES OUT TO VULNERABLE CUSTOMERS WHO GIVE IN ~ REST ASSURED GOD SEES EVERYTHING SO THEIR DOWNFALL WILL COME !!!

I’m customer with three for almost 20 years. I’ve upgraded my contact recently, unfortunately for much worse. Every single time I go abroad there is a signal problem. I can’t even contact three to solve it as my phone literally isn’t working. Apart from that, they charge me a lot for using my phone abroad, additionally to what I’m paying for my contact. It doesn’t happen to people I travel with who aren’t the three customers :).
Stay away from this company as they rip you off and when you call them the automatic response is: I’m sorry that you still experiencing the problem. Good bye. It is a joke!!!!

Been with three for 8years, the internet and network was awful, in the last few weeks I was not able to call or receive any calls for hours , just like that one day no internet and no network , and it was at home or in the city where usually should be working, avoid for any costs if you want to save your nerves!

Having cancelled my contract with Three,and been subject to a lot of harassment,threats and demands from them I was finally in a position to rid myself of anything to do with them except, I needed my PAC code to transfer my phone number,of 19 years,to my new supplier. The fun began again! I requested,in writing,3 times for the code to be supplied to me,without even an acknowledgement and, eventually I tried via their online chat mail. There followed a full hour long evasive, obstructive and unhelpful conversation which ended,after directly asking a further 3 times for the PAC code,with a promise to supply my with the code by email ( they claim it cannot be given directly via conversation). This conversation took place on Friday afternoon and here we are on Sunday evening with no code emailed to me. What a surprise! Or more accurately, exactly what I expected! The Three Customer Service is a joke and should be renamed Customer Non Service. Obviously,this is causing me a lot of problems but Three seems to care nothing about the effect and disruption they create.

Dealing with Tree UK have been an unpleasant and stressful experience.
Have been with them since 2006 and they literally made my life a hell.

I am writing to express my deep dissatisfaction regarding unauthorised charges made to my account following the completion of my contract with Three.

In [month/year], I entered into a 24-month bundle contract that included both a mobile phone and a monthly plan. I fulfilled all payments on time and, upon completion of the 24-month term, I reasonably assumed that the contract would be automatically closed, particularly since the device had been fully paid off.

To my surprise, I recently discovered that automatic direct debits have continued for the past 11 months, even though the agreed contract period had ended. When I contacted customer service, I was told that the plan was not cancelled because I had not formally requested it.

At no point was I clearly informed that I needed to manually cancel the plan after completing the payment term. Nor did I receive any notification or reminder from Three regarding the continuation of charges after the contract’s natural end. This lack of communication, coupled with the continued withdrawals from my account, is deeply concerning and suggests a lack of transparency and fairness.

This company is literally fraud . This company comes under CK Hutchison. They have took my money since 7-8 months . Due to glitch in their system while doing recharge my money got stuck . Since then they keep on closing my complaint according to their will.their executive are liers their executive tells me to return my money but since then they haven't returned it at all. There is a person name "sachin" who had given me a assurance of returning my money now he won't pick up calls. Their executives are rude also they are liers by reading of some kind of script . Please don't buy from this company they are literally "fraud" scammers . I'm going to the consumer court now.

Absolutely terrible phone provider, I have had nothing but lies from them since signing with them in December 24.
I signed a 12 month contract for £5 a month. Which is just going up each month.
I spend hours on the contact site, to hear more lies.
They promise discounts. Put them on my account page, then take more money from my bank. Wtf.

I have been waiting 2 weeks for this company to update my class code! Every time that I contact them they say that its in underwriting.
This company is not only super expensive but they suck!

I have cancelled my contract but they keep billing me threatening me with Balifs if I don't pay. The Indian call centre never really cancels it and gaslight me in everyday possible. Ie we have no records of the cancelation. I cannot get through via their Chat as I have a ZTE contract & I have lost the number. It lies between incompetence & fraud
