Sending single SMS message to multiple contacts causes MMS I'm experiencing an annoying (and costly) problem on my HTC Desire X. (Android 4.1.1) Every time I send a single message to multiple contacts at the same time, the message will be sent as MMS rather than SMS, even though it is a normal text message (not too many words).

I am using Facebook's messenger app to send 'normal' messages as well, but I don't think it has anything to do with it.

EDIT: okay, so after some testing I noticed it has to do with Facebook messenger's app. I went over all settings but can't seem to find anything that disables MMS for group messaging?
This is an easy problem to fix, I believe @BryanDenny already mentioned it. 


Go to the stock Android messaging app.
Click the Overflow menu button down in the lower left hand corner (it looks like three boxes stacked on each other).
Select "Settings" from the pop-up menu; should be the first option. 
Under "Multimedia (MMS) Messages, uncheck the item that says: "Group messaging- Use MMS to send a single message when there are multiple recipients".
