How much will I get for my old device?

[JessiJ]

I'm looking to do a device swap for my upgrade to pay off my remaining balance of my current contract. The form only gives you the option to click damaged or not damaged - you can't state how bad the damage is. The whole back of my phone is cracked even though the phone is in perfect working order so I have clicked casing damaged -  will they then deduct a lot more off it if I send it back? Am I better selling it myself?

You won't get a final assessment until they have seen the device.  You can either accept their offer (it will likely be quite low with that damage) or have them return it.

As an idea the retail cost to repair that damage is around £250.  (iPhone 14)
