The legal bit

The results are an estimate, but they will give you a good idea of the coverage you can expect.

This map cannot guarantee the availability of mobile services in any particular place. That’s because mobile reception can be affected by things like building materials, tree cover and weather conditions. And remember, to use 4G or 5G you’ll need the right coverage for the plan you’re on (whether that’s a 4G plan or a 5G plan), a compatible mobile device and an eligible BT Mobile plan.

4G+: limited roll out and select areas only. 10% customers in coverage will receive speeds up to 90 mbps, you’ll need coverage, a compatible phone and an eligible plan. Speeds referred to are download speeds. Just how fast your 4G will be depends on: where you are and how many other people are using 4G too.
