We have you covered.


iD coverage checker.

Find out the signal strength in your area. To check if you’re covered by our network, enter your home postcode below and choose the 3G or 4G map. You can also check other locations you visit regularly, such as your work address.

4G Calling is compatible with the following devices on iD: iPhone SE, iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, iPhone 7, iPhone 7 Plus, Huawei P8 Lite, Huawei P10, Huawei P10, Huawei P10 Plus, Samsung S7 and Samsung S7 Edge.



This map is a computer-generated prediction, so please use it as a guide only. We try to make it as accurate as possible, but it’s not a guarantee of actual signal coverage.

Please note: no mobile network can guarantee how strong your indoor signal will be, because the signal strength needed to pass through walls and other features varies from building to building.
