Coverage and postcode.

Tesco Mobile and coverage and postcode

Tesco Mobile is a separate account provider using O2 radio infrastructure. Tesco Mobile handles the contract even where the underlying signal is O2.

Compare the Tesco Mobile checker and Ofcom for a postcode; remember that building materials affect indoor reception.

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.

Use Tesco Mobile, not O2 account support, for a personal bill or SIM replacement.

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