LG V30 (SPRINT TO ATT) MMS AND UPDATES
Cannot send or receive text messages with pictures since we moved over to At&T. Also, phone updates no longer work. I get a message saying "authentication failure, contact your provider". Phone worked great before the switch. Already spent 2-3 hours w/AT&T tech help with no success and ticket is still open I'm told. Going on third week with AT&T and this is starting to wear thin. Not sure what forum this should be posted in.
