How Much is My Phone Worth?

How much we can offer you for your mobile phone depends on several factors. Such as:

  • The Model (Newer or more expensive models are more valuable)
  • How old it is (same as above)
  • How much storage it has
  • What condition it is in
  • Packaging
  • What network it is unlocked to

Having your phone unlocked and in its original packaging can help with its value. Bring your device with you to our SIM3 shop in Preston and we can determine a price for you.
