My galaxy s5 is converting only 1 number to an mms.

[Android Central Question]

They are not long messages so it has nothing to do with the size of the text. It is converting it to his att email address. With his number then @mms.att.net And in my contacts its just his name and phone number, I've deleted that email from my outlook and my phone. I did used to text to that email but now we are texting normally again and my phone is doing this with his number only. How do I get it to stop converting this one phone number to an mms message? All other numbers and contacts text fine.

Are you using the same conversation thread as before? If so, you need to start a new one with only the number.
