5G voice/text is not working and shows (5g:prohibited:) but data will "work". Have to run 4G even after getting new SIM from Tmobile. 5G was trash before this but its worth mentioning for the beta. I submitted an error report and encourage others to as well. 

5G will randomly come back but drops within a matter of mins and at uneven intervals. Does not automatically switch to 4G.

Make sure you have the correct SIM. They recently "realized" their original ones are not compatible with 5G.
