Roaming abroad.

Tesco Mobile and roaming abroad

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

The country and tariff both matter

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.

Find the destination in the provider’s current list and read any access condition or fair-use restriction.

• 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.
