JT’s Network Transformation Now Rolling Out in Guernsey
JT’s Network Transformation is now entering an exciting new phase as we begin our rollout across Guernsey — bringing enhanced 5G connectivity to more people across the island.
Following extensive upgrades, our focus is now on delivering improvements through a series of planned works in locations across Guernsey. This work is part of JT’s ongoing commitment to providing a faster, more reliable, and future-ready network for everyone — whether you’re streaming, working, or staying connected.
To support this progress, we’ll be carrying out scheduled work in the areas listed below. During these times, you may notice slightly reduced indoor coverage, but this temporary impact will help deliver a significantly improved mobile experience as our 5G network expands.
Who’s affected:
JT mobile customers in the listed areas during the specified times.
We’re proud to be investing in the Channel Islands’ digital future and appreciate your support as we continue to enhance our network across the island.
