Here at Three, we want our network to be the best that it can possibly be, so we work hard to identify faults and fix them as soon as possible. We also carry out regular maintenance work to keep our network in tip-top condition. And this means that from time to time, these network improvements can lead to service interruptions. So, when we know that we are going to be working in your area – we want to let you know as well!
The following is a list of the areas that we are currently planning to carry out work in.
Just so you know, this is not a live update of everything happening on the network – but we will be updating this list as often as possible. To check what your coverage is expected to be like, you can also check the coverage map by clicking here, and if you are experiencing coverage difficulties in areas not listed below, have a look at our coverage checklists below. 👇
