ADSI have managed my mobile phone contract for more than 10 years. Their customer service is second to none, always answering the phone promptly in response to my questions and queries. The Bill Manager facility is fantastic, really useful in easily allowing me to manage and control the spend on the whole of my contract.

Since ADSI have taken over our mobile phone management we have not had a single issue. They have even dealt with an ongoing problem that we had been trying to resolve for over a year! Dave is always really helpful and responds to any queries we have quickly and efficiently. I would have no hesitation in recommending them.

The staff at ADSI seem highly motived to deliver excellent service to their customers.  I have recommended them on a number of occasions because ADSI support is easily accessible and very clear.  I feel that if I have any issue with our phones, one call will sort it out.

We are really happy with overall service from ADSI; it’s great to have someone assigned to our account that can help us with any issues. Our overall phone costs have greatly decreased and we are  happy with ADSI

Our Account Manager worked really hard at sorting out an almighty mess created by our previous network provider, it’s great to have one point of contact and be able to have somebody who is prepared to take ownership of any problems that occur, and solve them immediately.

ADSI have been integral to our business growth providing a reliable and cost effective way to run an essential service to our company and staff who rely on constant communication. As a company and personally, they know exactly who we are and our habits so can advise and manage our services honestly and precisely.  You have to enjoy working with suppliers otherwise what’s the point? It’s an honest, open and thorough relationship that we are very grateful to have in our business life.

The fact that we have kept our business with ADSI in such a  competitive market for such a long time speaks for itself really. Service is great, always efficient. Clare manages our requests and queries promptly and efficiently with the bonus that she is always such a delight to talk to

Our account manager, Brad, at ADSI is faultless – I would highly recommend!  He helps with all queries, is knowledgeable & friendly, we feel confident that he gets us the best deal and gives us the best advice. We have saved a considerable amount of money over the years and the control we have over our mobile phones now is second to none. Any issue or query is dealt with promptly and efficiently, can’t praise highly enough
