Start by getting your free 2min phone valuation (Sell your Device) based on your device's condition. After answering a few questions, we'll provide a quote based on your phone's status. If you accept, you can send your device to us using our provided delivery options. Once we receive and inspect the device, we'll finalise the offer and process your payment.

Before sending your phone, ensure you've deleted all personal data, removed iCloud or Google accounts, and taken out the SIM and memory cards. We use advanced data wiping techniques upon receiving your device to ensure any remaining data is securely erased. Always remember to backup your data before resetting.

We use our diagnostic tool to assess your device's condition and provide an initial quote. Once we physically inspect the device, the offer might be adjusted based on its actual condition. If there's a change in the quoted price, you'll have the option to accept the new offer or have your device returned to you at no cost.

Once we've received and verified your device, we aim to process payments on the same day. The funds should reflect in your account by the next working day. If there's any delay, it might be due to bank processing times or issues with the provided bank details. Ensure you've accepted our final offer via email to expedite the payment process.
