Stop in for a cup of coffee

LTE is backwards compatible with most standards. But not 5g
But with the voice calls going to the 'enhanced' just having a 4G phone was not enough. Needed the brains to put the info through some sort of software or firmware. If my phone had the VoLTE in it, I'd have kept using it even though the g**gle aspects annoyed the sh*t out of me.

So I muddled my way through Straight Talk's lack of directions and new phone is working.
The old phone seems to be still working too. At least for now it may allow emergency calls and I think I can still use it for web access and as a hot spot. Out of curiousity I might test the latter two later.
