Really happy with our new phone system. The whole process was smooth and professional, from initial set up to installation. The team were helpful and knowledgeable and were available to answer any questions. We have been a customer of Comms Connect for a number of years and would highly recommend their services for any other business looking for a new phone system

After years of poor signal and being roped into the same false promises with an old network. We were recommended Comms Connect - and my gosh we will never go elsewhere ever again. Bev Robinson went over and beyond for us... listened to our frustration from our old provider... we were presented with a variety of offers to choose from... nothing was too much trouble! We got 2 of the latest handsets, we were talked through how to keep our existing numbers (as needed them for business)... and the transition was effortless! 100% recommend to everyone far and wide... Thank You Bev :-)

Great service from Comms Connect. They set up a VoIP phone system with a local business number for my landscaping company, which I can now use on Google and for advertising. Quick and easy set-up and very helpful throughout. Highly recommended.

We have now been enjoying trading with Comms Connect for quite a few years & particularly with Bev Robinson who has looked after our mobile phone accounts very successfully, she is always the same pleasant & communicative person, whenever we are speaking or emailing, she definitely goes the extra mile to make certain that we are always getting the product we require, at the best possible price & at the optimum time. We have recommended Bev & Comms Connect, to a lot of our business friends & will continue to do so, as far as we are concerned, it is a "one stop shop" for us, we are a company which is over 100 years old & we are firm believers in staying with the people who help & serve us well & that is Bev Robinson & Comms Connect, we would fully endorse trading with them.
