phone functionality doesnt work

I have a Samsung Galaxy Note20 5G. It installed a software update yesterday, and now I cannot make or receive phone calls. If I try to call out, it disconnects immediately (makes the sound like a call ended), and incoming calls go straight to voicemail without ringing. Texting and data appear to be working OK. How can this be corrected?

Hey @Treefrog99, you also want to verify that your LTE setting is enabled on your device. To use our network, a High-Definition Voice-capable (HD Voice-capable) device that is compatible with Cricket’s HD Voice network is required.
