Mobile phones and devices operate using an antenna to send radio waves over a range of frequencies or bands. These radio wave signals are transmitted to and from your mobile device through cell towers, network masts and base stations.
Each mobile network operator is allocated specific radio frequencies and bands that they can use to provide network coverage, and so the radio frequencies and bands that a mobile phone device supports determines which networks it can use.
Mobile phones sold within the UK are designed to work on all UK mobile network frequencies, and as long as the handset is unlocked (i.e. not network locked) then should work on any UK network.
If you are looking to purchase or use an imported mobile phone within the United Kingdom then it is advisable to check which radio frequencies are supported by referring to the technical specifications of your particular handset model, and crosschecking it with the UK Network Frequency Bands to see if the device is compatible with a UK mobile network.
