Refurbished iPhone 12 (UK) – Unlocked, Tested & Ready to Use

Want a refurbished iPhone 12 that’s great value and still feels modern? The iPhone 12 remains a popular choice for UK buyers who want an affordable iPhone with a sleek design, strong everyday performance, and features that still hold up today.

At Used Mobiles 4U, our refurbished iPhone 12 devices are professionally checked, tested and graded so you can choose the right balance of price and cosmetic condition. If you’re upgrading from an older iPhone, or switching from Android, the iPhone 12 is a reliable step up for daily use.

Which Storage Size Should You Choose?

  • 64GB: light users (calls, messages, a few apps)
  • 128GB: best for most people (photos, apps, streaming)
  • 256GB: ideal for lots of photos/videos and downloads
