In the US, many refurbished Pixel phones are Verizon variants which disallow OEM unlocking.

When was in college and had Sprint this was a nightmare since then I wanted root for unlimited hotspot (Sprint made it easy that way), but most refurbished Pixels were Verizon variants.

And I couldn't just use OnePlus because they were only designed GSM networks or later Verizon CDMA-less. Then, new Pixels were unaffordable for me, but parents insisted on using Sprint.

I ended up getting a Pixel 3 off Mercari (which I still own) just to keep root.

Now, I can afford a Pixel 10 Pro new (which I am right now), alongside spare Pixel 9 and OnePlus 13R units. But even then (a) my income is lower than when I worked at Microsoft and (b) The OnePlus was from a trade-in deal.
