5G not working after upgrade

[PaulS67]

I recently upgraded to 5G from 3G.  I'm using Samsung S21 Ultra. I can only connect to 4G+ network. With the 3G I was able to connect to 4G+ network as well and the speeds were the same 80 down and 20 up. I checked all the settings and the phone seems to be configured correctly. I read bunch of articles here but didn't see any magic bullets to fix this problem. Can anyone help?

@PaulS67- Accessing the 5G network all depends on where you are and where the nearest 5G tower is located.  Just because you signed up for 5G plan, doesn't mean that you will always have a 5G connection.  There are areas that simply do not have 5G coverage, or you might be too far, or there might be too much interference.

@PaulS67  You have to select 5G from your phones network settings . Also know that even in 4G /LTE you will still get better speeds then 100mbs of a 4G plan being on 5G plan with phone set to 4G/LTE do a speed test to confirm
