Well this is really odd did you try your sim card on another phone maybe the sim card faulty if it's a software problem did you try a factory reset. You can also try reinstall the stock firmware and software this is a more technical solution and for people that aren't adapt with tech might feel lost altrough I say most people in these forums can be quite knowledgeable of tech so I guess that isn't much of a problem

Well, it's a brand new phone (less than a week old) with the stock ROM using a SIM that's worked fine for the last 3 years in my 5X, so the SIM is known-good and resetting wouldn't seem to accomplish much other than be annoying having to do a bunch of app setup again.

Yes I know it's weird that it's behaving like that, that's why to narrow down the problems I want to make sure it isn't a software issue or rather an oreo problem I have heard that some people had issues with their s8 after the oreo update so. That's why I tell you to install or rather reinstall the firmware since this revert to it's factory version that I think it was nogoat

is the device up to date? Manually check for updates by going to Settings, Software Update, and manually checking for updates. It has probably been sitting in the box for so long, that the firmware it came with is more than likely way out of date. If you still have the issues after the device is fully up to date, then try a factory reset.
You mention the device is an unlocked Galaxy S8. Under Settings, About Phone. What model number is it? Under Software Information in the About Phone menu, What Service Provider Software Ver. does it list?

Hello,
Device is up to date with Android 8.0.0, patch level Jan 1, 2019.
Model is SM-G950F
Software version info in the screenshot below (also behold, my one bar, which magically changes to 4 bars consistently when I'm on a call).
Just because I'm trying to avoid resetting the device (which I just finished setting up and was a big pain in the rear), I tried booting into safe mode to test for issues caused by apps I've installed. The behavior was the same.

2 of 2 people found this helpfulThe F is a Exynos device and has a different radio than the SnapDragon versions of the device. Head over to XDA and look for one of the Combination ROM's that will make your device fully compatible with T-Mobile.

That's interesting. I didn't realize this was basically a different phone that would be unreliable. I have looked around XDA and haven't found anything yet, but I'll keep looking.

Check the cross device develooment section of their S8 forum. The Exynos CPU is slightly better than the SnapDragon but the GPU is slightly less performing.
