Dedicated Account Manager
With ADSI you will have your own dedicated Account Manager to handle your O2 account; a single point of contact should you wish to make any changes, add additional users or indeed have any queries answered. Your Account Manager will ensure you are on the best tariffs and contract for your business requirements today and in the future.
Should you experience any problems with your account or handsets your enquiry will be dealt with promptly and efficiently. In most case we provide a Loan phone for clients who require an immediate replacement handset for a faulty one.
Just think no more call centres!
Speak to our dedicated Sales team on 01268 495555 to discuss your existing O2 contract or for new tailored O2 business proposal.
Monthly Bill Reviews
As an ADSI O2 customer you will receive a monthly bill report and analysis by email which summarises your useage for the month. This highlights any over use, abuse, new expenditure on the account and we can advise on whether any changes are recommended and the cost effective solution for you the customer.
We can tailor the monthly review to your particular requirements; i.e. you may require a breakdown of bills for showing expenditure in different divisions or departments of the company. You may further require bills to be re-charged out.
Each report is sent from your Account Manager with a commentary, recent news from ADSI, top tips and a personal message.

‘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, Surrey
‘I would just like to say our Account Manager at ADSI has been brilliant, he has made the dealings with our Mobile Phone accounts so much easier and more professional.
He did indeed save us money and is very approachable, and goes out of his way to help us. He explains things so that we can understand from a laymen’s point of view as there are so many tariffs etc. available with mobiles these days.
I would most certainly recommend ADSI Group to any business colleague and have done so.’Ann Holton, Salco Group plc
Airtech Analysis Ltd were looking to save money on their mobile phone costs.
'We found the solution with ADSI; they were able to advise us on new handsets and recommend the company over to a better tariff business package to make substantial savings on their ongoing costs. We at Airtech now benefit from a single point of contact at ADSI that they can call to discuss all their requirements and furthermore receive regular comprehensive bill analysis of their accounts
We have seen a very substantial saving on our mobile phone bill charges over the past months' Gary Freeman, Airtech
‘We have been with ADSI for just over a year now and the service we have received from Matt and the team has been excellent. The main benefits from our perspective is having named points of contact who you can actually get hold of and who action requests without delay together with someone reviewing our tariff on an ongoing basis to ensure we are on the most relevant charging scale. All in all dealing with ADSI is a pleasurable experience.’
