More about your connection

Three SIM plans for UK connections.

Two services, with a 30-day minimum term

The Three voice and data option currently offered includes unlimited UK minutes, texts and data, subject to its fair-use rules. The mobile broadband option provides unlimited UK data for compatible data devices, with its own service conditions. Both currently have a 30-day minimum term.

Check Three coverage at the intended location and confirm your device is compatible. Unlimited describes the included allowance subject to fair use; it is not a promise of a particular speed or reception everywhere.

For use in the UK

These Three plans are for domestic UK use only. Roaming, international, premium-rate and non-geographic services are barred under the current plan information. If travelling or using equipment abroad is important, compare the actual included destinations and charges of a suitable alternative before ordering.

Once your account is ready, your Data-Fi platform provides bills and SIM-management options. We send your account access details separately.
