I'm not buying into 5G until the chipsets are all inclusive of all the bands. Most likely a later 2020 or 2021 5G chipset. Maybe a Qualcomm 875 chipset? I'm on FI and carrier hopping is what it is built for. Having all the bands makes sense to me in this case.
It isn't just the chipset. The X55 in the T-Mobile Note 10+ 5G is the universal chipset that works on all bands. So why doesn't it work on all networks? Antennas. 5G mmWave reception is difficult as even your hand will block it. The mmWave antennas needed are an extra cost item from Qualcomm and since T-Mobile is not planning to expand its mmWave network anytime soon, those extra cost parts are not included. It is for that same reason that only the highest cost 5G iPhones next year are supposed to work on all bands (they are all supposed to have the x55 modem, but only the top models are supposed to do mmWave). The cost (and room) those antennas require will be hard to fit. So there is no reason for the carriers to add to their costs and make it easier at the same time to move to another carrier. Obviously the future brings improvements, but mmWave reception issues are partly due to physics and not just a chip design issue. Perhaps the phone manufacturers will give the carriers no choice, but I think the carriers like the exclusive nature of the 5G phone. Time will tell.

Has anyone had problems with time and date thus affecting texts and so on?
One day the time and date changed automatically to something else. Texts were off because of it.
I went in and manually changed it and it fixed it
Odd, Shortly after I received mine on 12/6, a day or 2 after receipt, the date bumped up perhaps 5 days in advance. Phone calls and texts both had the wrong time stamp and that messed things up for days. When I saw it, I rebooted the phone and it fixed itself. Fast forward to yesterday and I look down at my phone and everything is OK. I look 5 minutes later and it is 3 days and 7 hours later. I was not actively using the phone at this time and it just changed. I again rebooted it and it fixed itself, this time thankfully before a text or call came through.
It was at this point that I realized that there is no apparent way to log some feedback. I had been beta testing 10 on my S10+ and there was a feedback option. But I don't seem to see a way to report this. It is obviously some type of bug.
Update - I did report it through the Samsung Members app. I encourage anyone that has had date issues to do the same thing.
