Unlocked is not factory unlocked.

I see an issue with many unlocked phones, are carrier unlocked, but not factory unlocked.

[Unlocked devices can generally be used on any compatible cellular network, rather than being restricted to one specific cellular provider. A phone can be factory unlocked, meaning it’s originally sold as unlocked. Or a phone can be carrier unlocked, meaning it’s originally just for one carrier, but is then unlocked by that carrier for broader use on other carriers (such as an MVNO). On Swappa, our unlocked device categories are for factory unlocked devices that are not and were not previously restricted to a single carrier.]

With what you say, any consumer/buyer is going to be conviced that the device they are buying is truly unlocked but I cannot tell you how many times I've gotten a phone that has it's bootloader locked by the carrier, meaning it is NOT factory unlocked. I am a developer and it's unacceptable to say one thing and do another. I really truly believe that is would be in this companies best interest going forward to be more strict on allowing what phones go into the unlocked category.

This is just a suggestion, and issue I want to bring to light.
