Review summary

Created with AI, based on recent reviews

Looking at 93 reviews, most reviewers were unhappy with their experience overall. Many customers reported consistently poor network performance, experiencing issues like buffering, lack of mobile reception, and difficulty using their phones due to bad signal, which significantly impacted their businesses. People frequently found the customer service to be unhelpful, with long wait times, unhelpful responses, and staff lacking communication skills, often leading to a frustrating cycle of explaining issues repeatedly. Reviewers also mentioned problems with contacting the company, being passed between departments, and receiving false promises of callbacks, making it difficult to resolve ongoing issues. However, some customers were satisfied with the competitive prices and deals offered, and a few praised specific staff members for being helpful, quick, and accommodating, particularly in local shops or with dedicated account managers. These positive experiences often highlighted faultless service, clear communication, and effective support for account changes or new SIM cards.

Having been with 3 for quite a few…

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…

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

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…

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.

Avoid at all costs!!!!!!

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…

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.

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.

Don’t start contract with this company other why’s you regret

I had a very bad experience with this network provider. I have never heard of this company before in the UK, and unfortunately, my SIM card has been inactive for more than two weeks.

I tried to contact customer service several times, but they only kept telling me to wait without giving any clear solution. The customer service team was also very rude and unhelpful.

Because of this experience, I strongly advise others not to start a contract with this provider. I do not recommend this service at all.

Three are a disaster case!!!! Simply don't do it! Don't go with Three!!

As a Three Business customer I wish to inform anyone thinking of joining Three about what a disaster my experience has been.

Simply, just don't do it! I have lost a morning of business today because of this company over a fault by Three. Potentially my company's credit rating might take a hit too which I will find out soon enough, I will seriously be disappointed if this is the case. Trying to communicate and resolve matters with customer services that have zero idea of how the UK works as they simply do not reside in the UK or can relate to how things operate here is a testing. I can see why Three opt to use or base operations abroad as there are much less hassle from UK regulations and tax but this comes at a cost whenever trying to speak to these people for help resolving any issues. For example, you have a person in Ireland supporting someone's business in Peru, what and how can that person in Ireland relate or advise on business issues or business impact and support the person in Peru, it's just not working. There is little to no business understanding... If the companies support and business is not in the same country then nothing in aligning... AI would do better but it's not the answer either... You need support and understanding from the support staff in the country your business operates from.

Three ooze cheap and nasty in mostly every aspect!
It's time for me to move away from Three.

Three can potentially very easily cost your company in loss of income, productivity, staff and can easily do damage to your company credit rating, potentially, I wait to find out!!! All of these points and the customers services reps have little to no understanding how important these matters are.

Just don't do it!
