It is interesting that T-Mobile has not announced any increases in VoNR devices or markets.
Dish really wants to offer all 5g services thus VoNR is essential.
If we look back at VoLTE early day issues, they were reportedly density (which was largely solved by several low bands), new switches, and new VoLTE standard "codecs". Wonder if we will have to wait for the x75 modem in the s24?
Hopefully people more knowledgeable than me will comment on this.
