iD Mobile uses the Three network for its mobile service in the UK.

Quick Scoop

  • iD Mobile is what’s called a mobile virtual network operator (MVNO), which means it does not own its own radio masts.
  • Instead, it runs on Three’s UK network infrastructure, so coverage and 5G/4G performance are essentially the same areas where Three has signal.
  • The brand itself is owned by Currys plc (the big UK electronics retailer), but all actual mobile connectivity is provided over the Three network.

What this means for you

  • If you are checking coverage for iD Mobile, you can safely look at Three’s coverage maps, as iD “piggybacks” on that network.
  • Features like 5G availability, call quality and general signal strength will broadly mirror what you’d get on Three in the same location.
  • iD then adds its own plan features on top, like data rollover, roaming in many destinations, and bill capping, which are commercial extras rather than a different underlying network.
