Using Alcatel Idol 4S w/Win10 & loaded up the June release last night. Was on WiFi so didn't notice until today that LTE is broke. Have 5 bars but no LTE symbol but more importantly, no data. Cannot pull up a web page unless I'm on WiFi. I suspect the load may have stepped on one of SIM settings but don't have time right this sec to spend with support to troubleshoot. Will advise when/if fixed.
In the meantime I'll use the Digits clone on my phone iPhone.
