You will need to have a phone capable of connecting to 5G, be connected to a mobile network that offers 5G, and be in an area where 5G has been rolled out.
5G has been rolling out across the UK since 2019, with different networks rolling out 5G at different times and in different areas. 5G requires additional infrastructure to be put in place, and is mostly being rolled out in certain cities with coverage expanding over time.
While 5G is in the early days of deployment, minor disruptions may occur during the LTE-5G handover as networks roll out their service. Samsung is working with mobile operators and will be offering software updates to ensure best performance.
We recommend contacting your network to check when they will be offering 5G and whether this will be in your area.
