MUST DO Checklist Before Buying Used Phones!

Thinking about buying a used second hand or pre-owned phone to save some money?

In this video I go over a the most important must do checklist before buying used phones either for personal use or for resale. I also included a list of the free websites that I use daily to completely check each phone before making a purchase to guarantee that I am buying a fully useable and functional phone.

Steps & Resources
Step 1 - Check cosmetic condition, functionality, battery usage

Step 2 - Check carrier and unlock status

Step 3 - Check national blacklist status

Step 4 - Check network block status

Step 5 - Check finance status

Step 6 - Check warranty status

What would be the UK version of these sites?

What do you do if you have a used phone and you don't have the security swipe pattern/code/pass for the previous person? Even hard resetting it with factory reset this still somehow keeps going back to the swipe pattern wanted by the previous user. So I'm stuck.

The cosmetic is what matters the least since you will use a case anyway, screen, full functionality, camera lenses condition and battery the most important.

Does that mean that if a device is not paid off it will be blocked by the carrier, BUT not blacklisted?

I wish your video would have went more in depth about checking the functionality of the phone. The actual steps and where to press to check these things (for example, the battery health).
