iD Mobile and coverage and postcode

iD Mobile is a separate provider on Three radio infrastructure. iD Mobile controls its accounts and written terms.

Test the places that matter and check both iD Mobile and Ofcom postcode information.

The terms that matter are those attached to your own service. An independent information line cannot view the account or confirm an individual balance, eligibility or coverage outcome.

Questions worth writing down.

Use the full postcode in the provider map and Ofcom Map Your Mobile. Compare indoor and outdoor results.

• Which document or provider page states the rule for this specific account?
• Does the handset, postcode, destination or start date change the answer?
• What happens after the current term or allowance ends?

Use the verified route.

Keep device repayment and airtime questions separate when considering a move.

For a change to service, a replacement SIM, a complaint or cancellation, contact iD Mobile through its own verified account or help channel. We can talk through general information without requesting credentials.

Check live information.
