Even in the US, the limited hardware support is a barrier right now, especially with having to find a unit that has an unblockable bootloader.

But it's still doable for many people. I most recently bought a second-hand Pixel 6a for GrapheneOS, and BYOD it to an inexpensive no-contract plan.

Pixel 6a units with unlockable bootloaders are currently $235+ on US eBay, which is less than new current Pixels and iPhones bought outright, but more than many lower-end devices, and more upfront than people pay for contract plans that toss in a phone.
