No 5G (or 4G option) on my galaxy s20

Hi, so I bought a galaxy s20 unlocked from Samsung last April for a while now I've been kind of confused as to why my signal never shows that it's in 4g. I've contacted my carrier and they've assured me that my phone is running on 4g data. Its a very obscure network company (h2o wireless) But I have no options under mobile networks for anything higher then 2g/3g/LTE. I was also told that my Sim card was not a factor as well. 

I've tried resting my phones wireless networks. And clearing out the cache after rebooting in safe mode. But to no avail. I don't know why the option for 4g won't even show up much less 5g.

There was an LTE only version of the S20 Ultra which was released and you may have bought one of those but I don't think the model number you provided is for an LTE Only S20 Ultra as the model number for the S20 Ultra 5G is SM-G988B or SM-G988U1

Please see my post above and let me know your baseband version. Also, please go to Play Store and download Devcheck app and report back with the processor info under the hardware tab.

Oh ok so it is definitely an Ultra 5G from the info you told me so I don't know why there wouldn't be a 5G option on your phone
