Does your phone say it's connected to the network?
Is it showing any errors
Can you use mobile data? Or any other netweork related options?
Like if you go to Settings > Connections > SIM card manager, are all the options grayed out?
Also is the correct SIM card set for Calls and Messages?
If all of it is correct, then please share an error report wiht us via Beta Feedback option in Samsung Members app.
Our development team will have to take a look at it.
