Got a much longer response identifying the mobile number & iPhone model as well as confirming that it was 4G capable ... & saying thanks for using the service.
I have a silly phone for old farts. Just recently I lost the facility to make and receive voice calls, but SMS and time syncing via the network were unaffected. Apparently, this happens if VOLTE is disabled. This was a common problem after the switch from 3G to 4G. I don't know why, but I had to reboot my phone to re-establish VOLTE, despite having no problems with it for several months.
