My phone keeps converting SMS to MMS even when messages are under 20 characters? I'm using a Samsung Galaxy Note and having enough trouble with the texts. I never even start typing and it says "Converting to MMS" the moment I open messaging and pick a contact.

I've already turned "Creation Mode" to "Restricted" and it did nothing. No one gets my MMS messages either. It's like I never even sent anything.

How do I make it stop?
I had problems with my texting immediately after leaving the Cricket store. This may not be your problem with the conversion, but as far as people not receiving MMS, try fixing your APN. You will have to research how to do it on your phone and get the correct APNs for your phone carrier, as I do not have access to that specific phone. This may at least help you with people not getting MMS from you.
