Map Your Mobile
Ofcom’s mobile checker shows which network offers the best 4G or 5G signal where you need it most. Once you put in your postcode, you’ll get two sets of information:
Coverage. This shows whether a 4G/5G signal is available locally, either indoors or outdoors, and whether the signal is likely to be good or variable. The results are shown on a map so you can move around and zoom in. 
Performance. This is the likelihood that you can stream video on your phone when you’re in your local area - that’s the district covered by the first bit of your postcode. We use dials to show this performance for each network.
Use of this checker is subject to Ofcom's terms of use.

Various factors can affect coverage, such as being close to large trees or buildings when outdoors, or the thickness of walls if you’re inside a building. This means there may be differences between the coverage prediction and your experience.
