What it is
iD Mobile is a UK mobile network that runs on Three's infrastructure. It offers SIM-only plans and phones, often at competitive prices.
Who it's for
UK users looking for a lower-cost SIM-only deal, especially if Three's coverage is good where they live and work.

Honest downsides
- Coverage depends on Three's network in your area.
- Some extras and roaming terms differ from the bigger networks, so read the plan details.
