5G Intermittent/Unreliable connectivity

[BlakWight]

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.

ever since T-Mobile has launched their 5G Network I have not been able to utilize any type of data services and can only use my device on Wi-Fi

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

[BrettTech]

yes I went to the store and upgraded my sim to a compatible one that was one of the steps I haven't had proper service in over 3 months so they've been crediting my account

[BrettTech]

they also told me there's a master ticket in because of a compatibility issue with some of these Samsung s series and other devices with their 5G Network and they're working on a fix for it
