I’m pretty sure AT&T (AweSIM carrier) has shut down 3G in my area. I am reluctant to experiment because of the nature of the text message as described in “2.” in message #1. I have an ereader that could download books over 3G that stopped connecting over a year ago. In any case, my L5 has never dropped down from 4G to 3G, although maybe that is attempted when mobile data is disabled, with VoLTE left enabled, as described in message #1. That is, I can not make calls on my L5 when mobile data is disabled, which is extremely annoying.
