** Mobile coverage: 99.5% coverage figure is based on outdoor locations of the Bailiwick of Guernsey. Source data is a computer-generated prediction obtained from Atoll, Sure’s network planning tool, as of 3 May 2017. In addition, Sure mobile engineers have undertaken drive testing in built up locations to validate the Atoll results. Coverage and speed may be affected by factors such as building materials, tree cover, other physical objects and weather conditions as well as how many other people are using the network. These results are a guide and not a guarantee of service. To access 4G speeds, you will need a 4G compatible device.
