Three Business Reviews 

The customer service is very variable. Sometimes the staff is very understanding and sensible at times they can be completey void of logic and unhelpful. They had terrible homebroadband connection for over 4 months and their engineers are still fixing it!

Always deny responsibility and blame other equipment. First line staff obstructive and unhelpful (and unintelligible). Try to push you off to CISAS

Very poor service, exit charges etc.
Never go into a contract

Good value on the face of it, but absolutely terrible network coverage and strength since Summer. Seems to coincide with the Vodaphone merger. Customer service has been poor, and slow, and basically make out there's nothing they can do and shrug their shoulders. Unfortunately will need to find another provider.

Absolutely by far the worst service i have ever had from any company ever.

Ordered their plug and play broadband hub. First set of equipment faulty and never worked, replacement delivered. Replacement didn't work by which time i had spent 10+ hours faffing and going around in circles on their customer service. Decided to cancel as within the 30 day cancel window but they "could not cancel because of a back office process issues that they needed to resolve" supposedly making a note to process it when the back office issue resolved.

Nothing happened and they collected the next months direct debit which i subsequently cancelled. Several months later, no refund and a snotty letter saying i owe several months payments else will go to a credit agency.

Call their customer service, position fully explained and acknowledged, placed on hold several times while they speak with other teams and then clearly binned me off as no one there after a further ten minutes on hold. Informed them at beginning of call to call me back if there is a problem but told they cannot do outbound calls and cannot send email correspondence - so basically its always on the user to keep phoning back going through the same loop.

Now on the phone again with another agent explaining it all over again and 27 minutes in and on hold again.

How they are in business is beyond me.

I bought an iPhone 15 and Three airtime together in November 2023. From my perspective, this was one overall purchase, but the payments were handled through separate Direct Debits. I continued paying my airtime every month and genuinely believed my payments were being dealt with correctly. I never intended to avoid paying for my phone.

I later discovered that the separate device-finance payments had not been successfully collected. When I tried to resolve the issue through the My3 app, I could not set up the device-finance Direct Debit there. Three later confirmed that I needed to call 333 to arrange it.

I feel Three failed to make the separate payment arrangements sufficiently clear and easy to manage. I was paying for my airtime while the phone payments were failing, and I did not understand what was happening until the situation had escalated to debt collection.

The matter has had serious consequences for me, including a £735 default on my credit file. I have disputed the circumstances and my complaint is currently awaiting a final decision from the Financial Ombudsman Service.

I am not denying that I entered into a phone finance agreement. My point is that I intended to pay for the phone and believe clearer communication and a more straightforward way to manage both payments could have helped prevent this situation.

This has caused me considerable stress and inconvenience. I hope Three takes these concerns seriously and improves how it explains and manages device-finance payments for customers.

This company is an absolute joke! Their 5G Business Hub needs to be avoided at all costs. My experience with Three Business has been nothing short of a nightmare.

I originally received a 5G Business Hub, but the connection was terrible. I discovered that my area only had 4G coverage, so I contacted Three and asked them to change the settings so the hub would only connect to 4G. They told me they couldn't do this from their end and instructed me to change the settings myself.

I logged into the hub using the username and password printed on the device. However, when I went into the settings, it told me I needed to disconnect the modem to make the change. The problem is that as soon as you disconnect the modem, you lose the internet connection and can't complete the change! What kind of ridiculous system is that?

When I explained this to Three, they told me the device was faulty and arranged an exchange.

The replacement arrived, and guess what? Another faulty device! Only one light would come on, and the internet speed wouldn't go above 10 Mbps. Absolutely unacceptable for a business broadband service.

I raised a formal complaint, and Three agreed to exchange the hub for a third time. You would think they could at least get the delivery right, but no! They delivered the third device to Norwich when I live in London!

Three faulty or mishandled hub deliveries, terrible internet speeds, poor technical support and complete incompetence when dealing with my complaint.

This is supposed to be a business service, where customers rely on a stable internet connection to run their businesses. Instead, I've been left wasting my time dealing with one problem after another.

Three Business, your service is an absolute disgrace. I have completely lost confidence in your company.

If you're considering taking out a 5G Business Hub contract with Three, my advice is simple: AVOID THIS COMPANY AT ALL COSTS! Save yourself the stress, frustration and wasted time. I wouldn't recommend Three Business to anyone.

Why is so difficult to speak with someone - mostly when you are a business and have limited time. Really annoying to wait so many questions and then someone that is very incompetent and not willing to help answers the phone. Very frustrating, I have 3 phones and 5 routers with three and I'm going to cancel everything. Probably starlink won't give me this headache.

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

Three you appear to have deleted your first reply which says “So we can help, you can contact us here - Customer Support Team on 333 from a Three phone, 0333 338 1001 from any other line, or via *link removed*
Firstly the link doesn’t work (also didn’t work for a lot of other customers either - Google searched it) and Secondly the number you gave me wasn’t for a business query.
Despite that, I spent 35 minutes on the phone and after being transferred to the right department spoke to someone who promised me, as all the others have, that I don’t owe anything as my account has been closed and he cancelled the direct debit. What happened hours after it??? Yes that’s right I got another bill with cancellation charges.
Please don’t reply with an automated AI response, this is an appalling level of customer service.
And where have you asked for more information from me? You surely don’t want me to post my business account number on here do you???

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.
