- Verdict:
⚠️ Proceed with caution!
All of OnePlus' phones are easily unlockable. However, do tread with caution as OPPO and OnePlus have merged their codebases into a "unified codebase", so OnePlus can, at any time, disable their unlocks. This means OnePlus, at any time, can completely pull an OPPO and lock their unlock process.
OnePlus also used to provide Deep Testing for their SIM-locked devices in the US, however they have stopped doing this.
