Trying to troubleshoot connectivity issues with Cricket so put the SIM card in my previous Samsung J7 that was used with ATT. They told us at the time it wasn't compatible but not the details. Got a message from them now that the phone doesn't have HD Voice. Calls don't work but text and internet does. Is HD voice a requirement for all providers for 5G? Just wanting to understand the details as I need to get a newer phone for Cricket and may go for a used one.
