one star is too many. This company are a complete joke and if you try and contact them and they don't like receiving complaints they cut you off continually

- I'll keep it simple as it's the only way you can have any type of dialogue with Three Mobile !!
I opened SIM only plan about one week ago , received SIM , activated SIM and all good , another week down the line awaiting for Three Mobile to set up direct debit as my details were given the day I took out the contract , then yesterday decided to make a call and guess what !!!!!!! I'D BEEN DISCONNECTED FOR FAILING TO PAY THE BILL!!!!!
The bill is not even due!!???
Folks my advice stay well away , they do not have clue!!?
Stay safe don't approach There Mobile!!!

I have never had such terrible service from any other company. Three have been really bad, it started with the agent getting my name wrong, the first letter, then to change the letter you need to send your passport and a utility bill, the you need to wait 5 days before anything happens. The ID network that uses the Three network is just as bad if not worse, you can’t speak to a person you can only use CHAT, and if someone can get a problem solved they will be lucky.

Doesn’t even deserve a 1 star.. took too much off me for two years (more than contract) and when I realised and questioned I was promised a refund of this.. over 2 months of promising I’ll have the refund, still nothing, the manager I got out forward to didn’t even know what month, day or year it was when I spoke to them. STAY AWAY FROM THREE! VERY POOR CUSTOMER SERVICE!

3 network is fantastic coverage. Unfortunately our router packed up. It's been nearly a month with no tv, wifi, Internet nothing. Customer service is rude, They are still receiving my money. Threatening us to keep taking the money from our bank. And receiving a CCJ. they have not providing us with a new router. Stating a further 30 days to get us a new router. Within the UK.
We would recommend nobody use 3 network.
Contract up in August..
Regardless of expense..I am taking my business to anyone else other than these
Rude nasty, horrible customer service.
Left hand don't know what the right hand is doing.
Absolutely useless.
Horrible people.

I have 3 phone and 3 Mobile Broad Band contracts. No problems except that 3 recently sent me an email telling me that my MBB router was now obsolete and as there would be no more upgrades or security patches I should phone them soon to arrange a replacement as the offer was limited to 4 weeks. That's when the problems began.
I phoned the given number and found it was a defunct line and was directed to their main contact number (A bottomless pit of frustrated customers). After exploring four menu options I found that none applied to the router problem. I tried using their "chat" option but "it" eventually gave up and connected me with a real person, albeit from far, far away and only online. After explaining the issue I was offered "a substantial" reduction (£21pm instead of £23pm) BUT, when I reviewed it, it only applied until the next increase in April - so I would have saved the magnificent sum of £2 whilst committing myself to a 24 month contract. The full contract rate would then kick in again. The "substantial" reduction was reduced to £16pm but I was then told that an upgrade replacement wasn't actually available, despite 3 stating it being so in their email to me.
So, over an hour of my life I won't get back!

When checking MBB rates on 3 it says that it isn't even available in our area despite having a MBB contract with them since 2020.

3 Customer relations is a myth.

Three are a waist of time, they are a bunch of time waisters , they are not the brightest of people and can’t get things done, they won’t answer questions, to be fair , I have waisted my money, effort and time on this network. Never again , I will go elsewhere.

Absolute pile of crap rude customer services and constantly crap signal always a network outage and I'm 2 minutes away from 5g mast must not be for phones after all looks like the conspiracy theory's are true either way iv had enough and I'm not looking for an alternative network as 3_ Vodafone are rubbish I wouldn't waste anymore money trust someone that has already tried

3 UK has gone down leaving customers without service.

Speaking to a 3 UK customer care worker, they stated - 3UK does not have the technical knowledge, technical support or the resources to work their (3UK) systems.

3UK can check its call records as to tge accuracy of the above quote.

In my opinion, for too long 3 UK has allowed been allowed to claim technical outage. However, there has been no improvement.

The 3 UK customer service operator refused to escalate my complaint stating there were too many customers calling into complain and 3 UK were overwhelmed.

Lamentable

very poor customer service

I upgraded a couple of days ago and on reflection, decided it wasn't the right one for me within the 14 day cooling off period . I spoke to Gemma, the manager, at the Trafford Centre store. She put me in the capable hands of Abs. He voided the update and found one better suited to my requirements. After some difficulties, because of 3's set up, he activated the new contract successfully. They were both very helpful and patient with me (a non tech savvy person). Thanks to both.

I network been down for 2 days
Not happy that 3 has no back-up
For when this happens

Spoke with Lewis at 3 mobile services, Hartlepool. He provided excellent guidance through all our various options to enable us to make sound decisions to suit our personal requirements.
Very professional and most helpful.

i was first attracted to 3 by a board outside showing the rates upfront,which i liked the look of.having recently left a much more expensive set up-i went in and found staff to be a godsend-giving me time to describe my needs,they actually listened to me and we reached an amicable agreement-i could not recommend them highly enough-oh i know.the student rate is even lower than mine !

Customers staying with you should not have to do the work to get the best new deal. The loyalty should be rewarded by treating us at least the same as new customers but in reality better. Be different. Don’t be just another massive greedy company that only offers good deals to new customers and rely on people with busy lives to just stay and accept that bills get higher and higher the longer we are loyal. Totally the wrong way round.
Only offering better deals when we threaten to leave is not the way it should work. I’ve been a loyal customer for 15years+ and a new customer gets a better deal unless I call up and say I’m leaving. Why should I stay?
Also, there was no agreed upon date given for my end of use of 3. You just cut me off, regardless of when my new contract is ready. As it happens, my new sim has been delayed, so I’ve had 2 days so far with no Phone. I would’ve have thought it would work up until I activated my new sim. After all this time to be treated like this sums up how 3 values its customers

We visited the 3 store at the Bullring in Birmingham. Jai provided expert and excellent service and we did our Apple business with her as a result rather than visit the nearby Apple store. Absolutely recommended.

Well here we are again. I gave a 1* review on 04/10/25. Three have decide I have missed a payment on 2 of their accounts in September and October 2025.
I do not have any accounts, phones, gadgets or deals with them. My last dealings with them is 4 or 5 years ago. Since then I've been with Virgin/02 and more recently Smarty, who are very good by the way.
Experian highlighted their error as my credit score has fallen. I'm fuming.
Since my previous review Three have done nothing to rectify their error. Is this a coincidence, but Three joined or were taken over by Voderfone not long ago. Has this led to account issues, Software problems or just incompetence.

I recently visited the Taunton three shop over some issues around my bills. I have tried the online help without getting any satisfaction. The gentleman who dealt with my enquiry was superb and really supportive. He has managed to reduce my cost by £10 immediately and in March he will reduce it by another £40. Brilliant in store customer care, thank you

I’m having network problems about a week now in Glasgow my phone signal keeps going off for no reason at all can’t even make calls or text messages or the internet phone the customer service about this issue 6 times say my my network issues will go back in 7 days please solve this out fast it’s absolutely disgraceful

It was good to start with but it went downhill. I had no WiFi connection on some days. One was one and half day! No communication,no text no email to let me know when WiFi was down or when it was up and running again. I feel that I should be compensate for WiFi loss connection. I had to ring three to complain but not interested to know. I am with a different provider now.
