SMARTY and roaming abroad
SMARTY is a Three-owned digital brand using Three infrastructure, with a separate account and plan journey.
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?
Calling abroad while in the UK is a different service from roaming outside the UK.
Use the verified route.
Check whether a change takes effect immediately or from the next renewal.
For a change to service, a replacement SIM, a complaint or cancellation, contact SMARTY through its own verified account or help channel. We can talk through general information without requesting credentials.
