Three Business レビュー 

The three network is excellent I'd love to give it the extra 1 ⭐ but there are so many things the network needs to improve on? Signal is the highest issue here especially in places today where the competition is doing better for example the underground stations remote areas I'm sure many people will agree with me.

Regarding this review I have since forwarded my concerns to Three via the Call Centre, Three Store and website and I have been dealt with fairly and promptly. The matter is to be resolved. Thank you

Three offers good value and we run our Internet using their mobile signal from a nearby tower. However (it was coming wasn’t it) the signal is now not as fast or strong and I guess this is related to their merger with Vodaphone and sharing masts. If it continues to get worse we will need to change providers

My contract renewal was done smoothly by helpful and friendly staff at Enfield branch. It goes without saying why it was a renewal.

The worst experience I've ever had in my life

Poor reception, and when I complained was told it’s a long-term issue. no quick fix. Online customer service agents were rude.

What amazing customer service and provider Mathew Buttery is for Three Business! Working and dealing in a fast paced business environment , it was an absolute pleasure to chat via the app with Mathew - all my concerns and questions were answered with professionalism and transparent ease, very clear and concise . Three business is the best provider, highly recommended keep your amazing professional customer service people very valuable.

The prices and deals offered by this company are genuinely competitive, and that was the main reason I signed up. Unfortunately, my experience hasn’t lived up to expectations.

Customer service over the phone has been disappointing — long wait times and unhelpful responses, which might be due to their offshore support setup. On top of that, the network performance has been consistently poor. Even in areas where they claim to have strong 5G coverage, mobile data is slow and unreliable.

Overall, the value is there on paper, but the service quality and network issues make it hard to recommend at this point

5G hub highly recommended - solved my business problem of a consistently very good internet connection. Customer services have been good and I have just renewed my contract for 2 more years.

I would like to express my sincere appreciation for the outstanding support provided by Jamie Morrison from Three Business Sales.

From the very first interaction, Jamie demonstrated exceptional professionalism, deep product knowledge, and a genuinely customer-focused approach that is rare to find. He took the time to understand our business needs in detail and provided clear, practical solutions without any pressure or unnecessary upselling.

Jamie handled every part of the process smoothly — including working on our re-sign with the Adapt 15 — and kept us informed at every stage. His communication is excellent, his attitude is positive and helpful, and he makes the entire experience effortless.

It’s refreshing to work with someone who not only knows their job well but truly cares about delivering the best service possible. Jamie is a credit to Three Business, and because of him, we will continue recommending Three as our preferred business network.

Highly recommended — thank you, Jamie!

I am very unhappy as I have not agreed to any new contract why should I continue with the new contract?

Working with our dedicated account manager
Lee Gillies is always available and efficient in supporting us with our account and extra requests.

Absolutely disgusting.
I did a top-up o my mobile only to find they have stolen my money and set my phone to make emergency calls ONLY.
I went on their live chat and the useless assistant Ahtashamdad (obviously in India) refused to listen, I even gave him the SIM number which he asked for, then he told me he could not locate it - it was one THEY sent me.
I have emailed them to make an official complaint and they do nothing, not even had the decency to respond.
I will give them the statutory 8 weeks and then I'm going to OfCom. I want my money back and phone re-set so that I can use it.
Nothing but conning ignorant thieves.

We have a business account and we mostly manage it through the Carlisle store. We started with 1 mobile we now have multiple our business broadband now 3 also. It was recently time for one of us to upgrade and honestly the service, advice and patience is unbelievable. What a team. We should probably use online and call centres to manage our accounts but in all honesty if it wasn’t for the Carlisle team we might have found a deal and switched but knowing nothing is a problem service, billing a quick pop in your made genuinely welcome and they really do guide you on what’s best for you.

If it was in my hand, I would have given 0 stars, Pathetic Coverage, Mis-Sold business broadband device as it never connects 5G, Disconnects frequently, 2 6 months with them and 5 months have been contacting their support, That too using my O2 Internet as hotspot as Three never connects, Blue light is the favourite light of device.
One word, Terrible customer service, Pathetic Coverage, Save yourself from Three business

I do not think I was sold a product that suited me, but as I am not back in the UK until late November then I will have to wait until then to pop back into the store to discuss this matter.

We signed up for a Three Business mobile contract for just under 100 users two years ago, and honestly, it could’ve been a nightmare. Instead, it felt like a spa day—thanks to Craig Maxwell (Customer Success wizard), who handled every detail as if he’d been secretly working for our company for years and treated our rollout like a personal mission. He’s so good, I’m having him written into the contract renewal.

We came for the product and price, but stayed for the customer service and the “no-panic, all-answers” energy (OK… and the price). The customer service bar is now set so high it needs oxygen masks. Other providers reading this: be afraid. Be very afraid.

Result: 97 happy users, multiple cost centres, one happy Utilities Manager, and an Accounts Team as quiet as a spreadsheet on a Sunday.

A special mention goes to Callum (the dogless), who proves you don’t need a pet to deliver award-winning support—just lightning-fast responses and a great sense of humour.

Hamish Kemp, advisor for the Customer Success team, provides incredible service and absolutely deserves a promotion. Give them a pay rise and please pass on my personal gratitude for their continued service.

Terrible Customer support, although their staff wasnt rude they were extremely unhelpful. Terrible signal and had nothing but issues since our swap from vodafone.

Terrible network in my area. I have complained severally and there's been no improvement yet.
