Why sell your iPhone 12?
The iPhone 12 introduced Apple’s first 5G lineup, a sharp OLED display and the reliable A14 chip. It still performs well today, but once it stops being used, the value drops fast. Selling or recycling it turns unused tech into money and reduces waste.
Selling your old iPhone before it loses value is a smart way to fund your next new phone.
Reasons to sell:
You get instant value for your phone, tablet or wearable.
You can send the payout on a new phone, or however you like.
Selling keeps good tech in use and cuts e-waste.
It makes upgrading easier and more affordable.
Your iPhone 12 shouldn’t gather dust in a drawer. It should give you something back.
What we accept
You can trade in more than just your iPhone 12. We accept a huge range of devices, including many iPhone models, Apple Watch, and handsets from other major brands.
Eligible devices are securely wiped and refurbished for resale, while non-eligible devices are responsibly recycled. Parts from traded devices may be used to support other devices, further promoting sustainability.
