There seems to be a dearth of used iPhones 6s' available around the £300 mark and I was considering buying one, however just trying to work out whether that's wise. A fair few seem to be upgraded contract phones although a few are supposed to be PAYG, some are locked to networks others not.
If I was to consider buying one, what are the key things to consider, so far I have.
1. Get one which has a receipt showing proof of purchase from the person I'm buying the handset from - to show they are the original owner of the handset.
2. Ask for ID from the seller, and have them sign a document\receipt noting the phone IMEI number of the handset, in case they later decide to report it lost or stolen, as they could make an insurance claim, and then the phone (mine) would be blocked with no recourse?
Any other words of wisdom?
