Y1619288971469 , via OnePlus 9 Pro , Jul 24, 2021 : I own a OnePlus 9 pro us version and 5g is lock on my phone for overseas communication using Zain 5g in Kuwait. Probably this will be my last device from OnePlus i pay for this phone to have great experience, it does has heating issues and more. But this 5g bug is bothering me and the Volte also wifi calling doesn't work since i am always in an area with no service. They said update and i waited a lot for updates. Fine i understand you need to test 5g man but at least put a way in development mode or debug something like that. That 5g will work but not promising at least allow the nr band. This is annoying when bands are not working because the sim car is from an overseas company. I contacted support many times and they don't care and give false information saying that the problem is on my side and not theirs. I feel like swapping my phone or using this as my second phone if those stuff aren't working. I live in a bad service area as well so i can't always get calls since wifi calling is not working. I wish OnePlus made a way to allow them on developer options if "they are not ready to release it "
