Independent comparison
Compare UK SIM-only plans by data use and coverage
Compare UK SIM-only plans using real data use, coverage where you live, contract length, roaming and total cost before opening a provider.
Start with the shape of the decision
A SIM-only comparison is useful only after the allowance is right-sized. Coverage where you live and work, contract flexibility and roaming can matter more than a large unused data number.
Free checks first
- Read the last three months of mobile data use on your phone or bill.
- Check coverage at home, work and regular journeys using provider maps and experience.
- Confirm whether the existing handset is unlocked and still supported.
