'ADSI have provided Astrum with an outstanding service over the past year and more. My Account Manager is always helpful and available to take calls and solve any issues we have with O2. Astrum have a number of company mobile users with a high proportion who work abroad for lengths at a time which can result in high usage of calls and texts and often problems with network connections. The team at ADSI are always on hand to work through these difficulties.

I would recommend ADSI to any of my customers when looking for great service and competitive prices."

Joanne Payne, Assistant Procurement Manager, Astrum UK

’we have been with ADSI for just over a year. Most people’s experience on switching any sort of service provider is that they are promised the earth; get good service at the start and this falls away. But with ADSI we received and continue to receive a personal and efficient service which despite today’s competitive market would be hard to beat.’

Simon Bradley, Discover the World

‘Our general view is that ADSI have delivered excellent service. Personal service is always a huge bonus when it comes to dealing with the sometimes complex subject of telecoms, and our account manager has always been efficient and responsive. The main purpose of moving over to ADSI was that we wanted to achieve a better and more cost-effective solution for our mobile phones. The cost savings have been significant and the contract costs are scrutinized every month by our account manager, followed by a written report and analysis. The contract is then adjusted accordingly to best suit our requirements.'
