What eSIM changes
The eSIM replaces the physical SIM profile. It does not create a new category of plan or change network coverage, calls, texts, data or renewal.
Existing members should use the account’s official replacement or conversion workflow so the number remains attached correctly.
New line and number transfer
A new customer can activate an eligible eSIM, while an existing member can replace a physical SIM. Porting from another UK carrier uses the normal account and transfer information.
Complete activation before deleting the old profile or cancelling the previous provider.
Using giffgaff abroad
UK plan benefits can have one roaming treatment in Europe and another elsewhere. Check fair use, data, calls and texts by destination.
A separate travel eSIM can supply data while giffgaff remains active for the UK number on an unlocked dual-SIM phone.

Purchase, setup and support checklist
Before relying on giffgaff eSIM, sign in to the actual carrier account and verify the exact line, plan family, destination and add-on status. Carrier international benefits are attached to an account and line; they are not guaranteed merely because the phone displays the carrier name. Save the current rate or pass screen showing Service: UK mobile line; Number: UK number included or transferred; Calls & SMS: Plan allowance; Activation: giffgaff app.
- Confirm the account is active and the exact destination is supported.
- Record the pass start time, end time, data allowance and overage behavior.
- Verify whether hotspot is included or uses a separate limit.
- Keep the carrier support number and account PIN available offline.
