I am very sorry to hear that your S9 after an update is unable to make or receive calls, and can understand the inconvenience and frustration. The first thing to try is resetting your network settings. You can do so by going to Settings > General Management > Reset > Reset Network Settings > Reset Settings > tap Reset to confirm.

If this doesn't help, there is also the possibility of a third-party application causing this device behavior. You can check for this by using this guide for Safe Mode: https://www.samsung.com/us/support/answer/ANS00062983/

Last thing to try is a factory reset. Please make sure to back up everything beforehand that you do not want to lose (using this guide on backing up files and data: https://www.samsung.com/us/support/answer/ANS00060517/) and then perform a factory reset to see if the behavior persists: https://www.samsung.com/us/support/answer/ANS00062029/

If the troubleshooting is not helpful, the phone will need to be evaluated by a certified technician. For service in the U.S., you can take the phone to a local U.S. walk-in service location https://www.ubreakifix.com/samsung or to ship the phone in for service, call 1-800-726-7864.

I found that once you do a data network update, make sure to re-sign into the network. When I did a data network reset I lost my data connection and had to reconnect to the data network.
