on android devices it should be ##72786# on the dial pad.
Hi, I was also having a similar issue. I have an S8+ that we have turned off multimedia for so long than turned it on about 4 months ago and it has still not been able to let me send MMS to anyone besides the 2 people on my plan. Is there anything you can suggest?
Hi hallett14! When was the last time you tried to send a MMS to someone and is it displaying failed to send?
