I just got a new factory unlocked Galaxy S20 model SM-G9810 (Dual SIM). I want to know if T-Mobile 5G is working on this phone. I can set the Network Mode to “5G/4G/3G/2G (auto connect)” but never seen the 5G show up in the status bar at the top of the phone.

I am wondering about certain features working on US version of the Unlocked phone.  The Dual Sim model is the International version and Tmobile 5G is in Band 71 600 Mhz.  .   I don’t see that your phone being the International version supports Band 71.  Thats where Tmobile 5G is.

More than likely, no.  It does not support the correct N bands to use 5G on T-Mobile.  It should work fine for 4G, as it has most of the 4G bands T-Mobile uses.  Whether or not you can get VoLTE working though is also another concern.

5G: n1/n78/n79 

4G: LTE Band 1/2/3/4/5/7/8/12/13/18/19/20/25/26/28/34/38/39/40/41

3G: Band 1/2/5/8 / GSM: 850/900/1800/1900 MHz
