Getting the most for your iPhone 15 Plus
- Compare before you post. The same 128GB iPhone 15 Plus is worth £206 at one store and £269 at another.
- Grade it honestly. Every store inspects the device; if it is worse than described you get a lower revised offer.
- Turn off Find My first. An Activation-Locked iPhone is rejected or returned. Our preparation checklist covers every step.
- Check if it is unlocked. Settings → General → About → Carrier Lock should read “No SIM restrictions”. Why it matters.
