They might be able to switch your old plastic sim back on (assuming you still have it), or help get you logged into your account.
Alternatively you can visit your local o2 store, with photo ID, to get either a new plastic sim or the eSim QR code.
Please note, this is not customer services and we cannot access your account. Do not publish personal details (email, phone number, bank account).
