Same here. Shentel has a very good network and handing it over to somebody else would not be wise. Allowing Shentel to combine the two networks and then totally manage the resulting network will result in one "KILLER" network. Nobody will beat it.
The missing CDMA data on Samsung devices that have updated to Android 10 is not related to VoLTE, it is a bug in Samsung's update. I have a workaround in testing that seems to resolve it.. hope to get an app update rolled out tonight for everyone!
