Myself and a co worker are unable to send any MMS/picture message or group text message while WiFi is enabled. When WiFi is turned off, they work. Everything else works perfectly with WiFi enabled. I have worked with Tmo support for over 2 hours with no fix. We have tried changing the APN protocols, reboot, SIM update, WiFi calling enabled/disabled even went into developer mode and forced mobile data to stay enabled while on WiFi and nothing works. Samsung said it's a carrier issue. Anyone else seeing this?
