The MMS messages must need a data channel to send/receive, as we established earlier. So when there is no cellular data available, the MMS messages should not work until the device connects to a WiFi network. However, if you can send/receive MMS messages without a WiFi connection, then it’s intriguing.
As for SMS, if they don’t work until the device connects to a WiFi network means the RCS features are in use on the device. The RCS also needs WiFi or data to work.
Please keep us apprised.
STILL and issue..., I have a Note 9, MMS worked fine on wifi with data off...now, just a week ago I combined accounts (only) "upgraded" to a new more expensive data plan and WOW...so many issues...from no text (sms or MMS) to just sms data on, wifi on or off..now no mms with wifi..only data...so let me get this straight before spending yet another infinite black hole worth of time waiting/speaking with Rogers (actually the techs always seem to be pretty good...csrs on the other hand...whoa!)
