We recently had our WiFi system upgraded by Crystal Voice & Data, and I can honestly say the service was outstanding from start to finish.
Paul and Alex did a fantastic job with the installation. Our old system simply wasn’t working for us — we had constant dropouts, poor coverage, and unreliable speeds that were affecting day-to-day operations. They took the time to properly assess the building, explain what needed to be done, and install a system that has completely transformed our connectivity.
The installation was neat, professional, and completed efficiently with minimal disruption. Since the upgrade, our WiFi has been fast, stable, and consistent throughout the premises.
Highly recommend Crystal Voice & Data — especially Paul and Alex — for anyone needing a reliable, properly installed WiFi solution. Excellent workmanship and service.
We had a voip of Crystal voice and data and it’s fantastic
I had an excellent experience with Crystal Voice Data! From start to finish, their team was professional, knowledgeable, and incredibly responsive. They took the time to understand my needs and delivered solutions that exceeded my expectations.
The service was prompt, communication was clear, and everything was handled efficiently. It’s refreshing to work with a company that truly values customer satisfaction and goes above and beyond to ensure a smooth experience.
I highly recommend Crystal Voice Data to anyone looking for reliable and high-quality service. I will definitely be using them again in the future!

I was looking to change my current virtual land-line provider when I came across Crystal Voice Data. I was impressed by the service offered, I was able to keep my number and on the porting day everything went smooth, I don't think I even noticed any disruption. The app is pretty good too and allows you to call from your mobile and is easier to use than my previous provider. Thanks to Alex at Crystal Voice!

After being let down by several other companies, I was beginning to lose hope in finding a reliable team to install a new VoIP system, network, and WiFi access points. Then I came across Crystal Voice and Data, and they completely exceeded my expectations!
From the start, their professionalism, expertise, and attention to detail were outstanding. They took the time to understand our requirements, recommended the best solutions, and executed the installation seamlessly.
The team was punctual, courteous, and incredibly knowledgeable. The VoIP system works perfectly, the network is fast and stable, and the new WiFi access points provide excellent coverage throughout the premises. They also took the time to walk us through everything, ensuring we were confident using the new setup.
I can’t recommend Crystal Voice and Data highly enough! If you’re looking for a company that delivers top-notch service and reliable solutions, look no further. Thank you for your fantastic work!
Would definitely use them again in the future!

We had used another company for years and were never fully satisfied with the service, but we didn't realise that there was better options until we met Alex from Crystal Voice Data. He has helped us get set up and explained everything clearly and is porting our current number across. All super easy and I would have no hesitation to recommend this company to any business that are looking for telecoms systems for their business

Svar från Crystal Voice Data
I met Alex last year, at the time my business wasn’t quite ready for his services but that time came and Alex was the first person I thought of!! He’s a lovely guy and is very honest and transparent. That plus being very knowledgeable with his products and he offers a very quick and efficient turn around. Would highly recommend him and will be recommending him to everyone I know who requires this service.

Great product and service.
We are really pleased with the phone system and installation service supplied by Crystal Voice Data. Training on how to use the system was very thorough and any questions we have had since have been promptly answered.

Svar från Crystal Voice Data
Alex from Crystal called out to review our systems, he identified immediately that our current provider had provided substandard equipment. One of the reasons why we had been experiencing a lot of problems internally with our connections.
We’ll be leaving our current provider and moving to Crystal VD.

Svar från Crystal Voice Data
Supplied me with a very memorable landline number which is linked to my mobile phone so I can always answer calls even when not in the office.
Gives a professional feel to a small business when you haven’t always got people in the workplace to answer the phone.
Also received helpful and prompt response to any questions or queries.
A great service…. Highly recommended!

Svar från Crystal Voice Data
