Three Business Reviews 

I was advised by Three to cancel my business contract as they couldn't get a signal to my Three Wifi hub, which was odd as the signal had been perfect and I was getting a decent mbps with it prior to it deciding to disappear (rural Scotland).
Three said it was a mast problem and that as they couldn't do anything about it they would waiver the cancellation fees.
So far I have had 6 bills that include cancellation charges.
I had been told on many occasions that I won't need to pay them as the balance is zero and there is nothing to pay. I have the names of the people and they all say the same thing that my account is showing there is nothing to pay.
I asked for that to be emailed to me (I already have the original stating that there will be no cancellation fees) but they can't email me as they "are not allowed to send an email manually"
Ironically I have now spent three hours on the phone with them and still the bills come...
If you read this Three, this is far from acceptable. That is time that I cannot dedicate to running my business

just tried to order a replacement sim card.
their online AI is useless and cant help and when passed to a human on the chat they were equally useless.
will be moving to another supplier...

Worst customer service. A customer since 2013, had 9 contracts at one point for years now down to 2. I’ll be leaving with these as well. From inaccurate or double billing to service issues that have plagued this relationship we are just done with them now.

Heads up when you renew a contact you have to buy bolt ons or pay £2.75 or more a day to use your allowances in Europe (currently in France arrived this morning by car. Staff will argue with you that it’s £2 and then say if you don’t want to put a spend cap on then you’ll have to find some WiFi ( never had one). Then they will argue that there would be a text message stating £2. Not received just a generic welcome one. Strange how in June this was not the case and then that was argued with me to.
So both numbers will be being transferred once I’m home.

I have been a loyal Three customer since 2011, and for the last two years I have had a Three Business account with four SIM cards and two mobile phones.

Unfortunately, my experience has been extremely disappointing. Whenever I visit the Meadowhall, Sheffield store, the manager treats me disrespectfully. He speaks to me in a rude and dismissive manner and has even told me that he cannot understand what I am saying. I found this upsetting and unprofessional.

I wanted to cancel my business contract, but I was told I would have to pay the full remaining cost of the agreement. This was especially disappointing because I had renewed my contract only 15 days ago and was already experiencing poor customer service.

I have also received conflicting information from Three. Whenever I call customer services, I am often told that my name does not match the account. However, when I visit the store, they confirm that my name is correct and say that customer services should not have given me that information.

To make matters worse, the network coverage and service have been very poor. I have experienced ongoing issues with the network, which is one of the main reasons I wanted to leave.

After being a loyal Three customer for over 15 years, I expected much better treatment. Instead, I have felt undervalued and frustrated. Based on my experience, I would not recommend Three Business Mobile to anyone. I hope Three takes this feedback seriously and improves both its customer service and network reliability.

What a joke, broadband did not work, I cancel it in 24 days they still charge me, I HAD TO CALL 7 TIMES TO RESOLVE IT, EVERY CALL TOOK 20 min on average.
WAST OF TIME!!!!!!!! AVOID AT ANY COST. CUSTOMER CARE IS HORRABLE!!!!!!

My experience with Three's complaints process has been extremely disappointing. A straightforward issue has taken months to resolve, despite numerous calls to customer service.

I was repeatedly promised that my refund would be processed, but it never arrived. On one occasion, I was even told that someone would call me back with an update, but no one ever did.

The complaints process feels unnecessarily difficult, with little communication and repeated promises that are not followed through. I don't mind waiting for a genuine investigation, but I do expect honest communication and for commitments to be kept.

I have now had to submit a formal complaint because I have lost confidence that this matter will be resolved otherwise.

STAY AWAY.

This review will be long but that title is the gist of it.

I was with Three for a few years for just a phone contract and I would warn anyone that values their sanity to stay away. Data is the most important aspect of phone bills these days and Three had so little coverage or maybe weak coverage that I think I spent more time asking for a hotspot or searching for wifi than I did using their "service". The reason I stayed for as long as I did is because they are impossible to get ahold of. I have spent multiple occasions on the phone chatting to some halfwit AI for longer than is sensible for anyone. So I decided I would walk into town and speak to a person about cancelling. They said there was nothing they could do and I had to go through the customer service lines. It seems that the shops sole purpose is to get other suckers like me to sign their souls away. I would rather have the highstreet die than interact with another one of these stores. Finally I got through to an actual person (I did this by ignoring the AI and staying quiet until it got confused and passed me along to its deceitful overlords). There I spoke to the guy and explained my position and that I wanted to cancel my contracts (I had two because at the time of joining on it worked out cheaper to have two than just one) he assured me both would be done. I thought that was that but no, months later I went back onto an old bank account and it had been eating into my overdraft, sadly the bank account couldnt send me their texts warning me because my contact number (contract 1) had been cancelled but my other contract still remained bleeding me dry. I got back on the phone to cancel again. Finally it seems to have stuck but not after needing to pay for one more month because I "didnt give enough notice". I couldnt believe my ears and I tried to argue my case but I presume the workers are kept in the same small cage by their bosses that we are by their contracts. In the end, I agreed to pay the amount but the truth is that he couldve squeezed me for more, I wouldve paid double to never have to deal with this company again. Just stay away from this provider.

Having been with 3 for quite a few years 5 lines and broadband I thought I change but on ringing and getting a new deal which was better than other providers I decided to stay. I live in Sheffield work in centre thought with this Vodafone merger it would be better service WRONG it is terrible middle of Sheffield outside cathedral buffering??? As for my broadband I got a new hub as my old one was three years old and salesman said a new one would work better (no difference) as for trying to set my new hub up was a nightmare password on new hub didn’t work rang customer services (India) got fed up of repeating myself had to end call emailed man who sold me hub several times no reply (Kevin) in the end I figured it out myself KEY was password?? Terrible customer service spoke to a man who promised to call me back later in afternoon who promised to sort it out never heard from him again. If you send message or chat all they do is tell you to use there postcode checker to see there coverage. Only good thing is there prices but then again is it worth compromising to save a few quid will definitely be leaving after this contract

Appalling broadband provision with three 5g business hub. On taking out contract on aug '25 the network performed reasonably fast for first month ('contract cooling off period') but once contractually locked it markedly declined. Sent the company 6 speedtest returns most below 1mb per sec for uplink with the lowest at 0.3 Mbps. Complaints procedure basically a runaround with conflicting 'doing our best blah blah blah' but you're contractually locked in and you better keep paying or we'll damage your credit score and ultimately send bailiffs round if I unilaterally out of complete frustration cancel the contract.

WiFi broadband never works. Lost thousands in business as we operate on VOIP calls. Customer service always treat you like your a problem. Based in India they don’t understand what you saying. Always feel as though problems with three take hours to resolve. Will be switching to Starlink. Wanting to get out of contract as have no internet

Do not use three business. We have no signal at our home/business address so can’t run our business. We are losing money every day because customers can’t reach us.

I have been a customer for many years and currently have four SIM-only contracts. Before they rejoined Vodafone, the price shown on the website was the price you paid.

Now, the advertised price excludes VAT, and you only discover the actual cost by reading the small print in the agreement. I find this misleading and far less transparent than before.

Had I known this, I would have reduced the number of SIMs on my account. Instead, I am now tied into a 24-month contract. Long-term customers deserve clear and upfront pricing, not surprises hidden in the terms and conditions.

Very good and fast reply. Excellent service and great customer care. Thank you.

Over the past few days, I have spent in excess of five hours attempting to resolve what should have been a very straightforward matter. Unfortunately, the experience has been unnecessarily stressful, time-consuming and highly frustrating.
I contacted customer services via 333 on several occasions and found the support to be unhelpful, inconsistent and lacking ownership. I repeatedly explained my concerns regarding unexpected account charges and the absence of a spending cap on my SIM account, yet no one was able to provide a satisfactory explanation as to why this was not discussed or applied when the account was originally opened.
Historically, I have never exceeded a monthly bill of approximately £50 on what is fundamentally a £10 SIM-only agreement. As a customer, I should have been properly advised regarding spending caps and budgeting controls at the outset. Had this been correctly explained and applied, this issue could have been entirely avoided.
Adding further frustration, I repeatedly failed security checks due to poor internal administration on their systems. I was asked numerous times for my business name, however it later transpired that the company details had incorrectly been recorded against an address reference rather than the actual business name itself. This internal data input issue caused unnecessary delays, repeated questioning and considerable inconvenience.
In contrast, I would specifically like to recognise the outstanding professionalism and customer care shown by the team at the Orpington store during my visits on both Thursday 14th and Friday 15th May. The staff members were courteous, approachable, proactive and genuinely willing to help — a complete contrast to the experience received through telephone support. They assisted me in understanding how to apply a spending cap correctly and importantly guided me to contact 337 directly, which ultimately led to progress being made.
When I finally reached the team at approximately 3:13pm today, I spoke with a very polite and apologetic gentleman who attempted to assist and offered a £10 goodwill credit. Whilst I appreciated his manner and professionalism, I do not feel this adequately reflects the level of inconvenience, poor service and significant amount of time wasted attempting to resolve matters which stemmed from failings within your own systems and customer support processes.
I have genuinely lost confidence in their telephone support service, as it appears the customer journey is failing at multiple stages — from account setup, to security processes, through to issue resolution.

We have been a 3 Business Customer for 6 months. There seems to have been a patch that has been run on Friday last week which has rendered our gateway unable to communicate. Having called the business customer service multiple times to try and speak to someone who understands the matter the constant message we keep receiving is due to a large demand in the area they are happy to cancel our contract for free. However it has been over 36 hours but unable to contact a technical manager as no call back received. Never heard of a company ready to shed customers instead of trying to understand the issue. Hopefully someone from 3 will read this and ask if they can contact us. Not sure they seem to understand reliability of their service for a business.

yet again after leaving a review they have fast been to fix the problem. 3rd month now I have paid for this service they claim to not have received it even tho I'm sending them transactions id and statements ect.
Happy to take my money but not give me the service or any reimbursement for this.

This is the poorest business network I have ever linked with in my life time. I couldn’t believe that there staff didn’t know their business rules, regulations and procedures.
In conclusion they didn’t know what they are doing.

Great assistance to sort out our new deal. Friendly knowledgeable gentleman. Very happy.

Everything...misinformation, chea....

I'm with three on personal number for ages but business is just a bunch of thieves...
