Tamar Telecommunications head office.

Tamar Telecommunications® is a trading name of Kalnet4u Ltd, trading since March 2002 and incorporated as a limited company in February 2003.

In 2011 Tamar Telecommunications® became a network operator in its own right. We provide a range of business telecom products and services designed and managed by our in-house team of technical engineers. Our services are constantly evolving to meet the needs of the modern day business. Our core services are the provision of 0800 numbers, 03 Numbers and local geographic numbers (virtual landline numbers) for over 650 UK towns and cities.

We have been providing telephone numbers for businesses for over 17 years and believe that our numbers and services can make a real difference to your business.

Over the years we have built up a large loyal customer base made up of small businesses, local councils, national charities and large corporate companies employing thousands of staff around the world. As a company we can adapt our approach to suit the sole trader through to the large corporate clients for whom we provide a dedicated account manager. Many of our new customers come to us from referrals from our existing customers recommending our services to them.

What our customers say…

A pleasure to deal with

I have spoken to Abby this morning and she answered all my questions fully and I must say extremely polity. Abby was efficient and a pleasure to deal with thanks tamar communications.

M Dawson

100% reliable

Just wanted to say how impressed I am yet again with your service, we’ve had a number translation with you for about 10 months and just added 2 more today. It’s always quick and pleasant dealing with either the sales or customer service departments, the numbers are easy to use, easy to setup, 100% reliable and a fraction of the cost some cowboy was insisting his (other) company had to charge us when we were first trying to setup the service. If only BT could learn some tricks from you guys. Many thanks again and keep up the good work!

M Lee

Customer service absolutely first class

Many thanks for all your help. I tried to set up this arrangement with BT originally and after countless phone calls and being left on hold whilst they communicated with their ‘back office’ every day for the past week I gave up trying. Not only that but they were going to charge me nearly £40.00 per month for each line and their call charges were double yours. You have connected me in less than an hour, your customer service has been absolutely first class and I am getting the service for a fraction of what I was ready to pay BT. I intend to recommend you to all the other Franchisees in the group using our online forum. I am a very happy customer!
