Charges for mms

[Anonymous]

Hi,
After turning on my Galaxy S4 a text was waiting for me asking if I wanted to set up mms (and wap I think)
I couldn't send a text so figured it was because I needed mms setting up so did that via web chat.
I have unlimited texts and minutes in my contract and have noticed when I log in that there are charges for mms.
I thought mms settings was something that I needed to be able to send texts. Is that not the case? Should I just ask to have mms removed from my phone to avoid charges and if they're removed will I be able to send text messages?
Thought I would ask here first because the phone and web chat take so long!
Any help or advice much appreciated.

This turned out to be one of those perhaps rare occasions when getting a live chat response was quicker than a reply here. Complete novice with android and still learning but really nervous at racking up extra charges so will leave it disabled until I'm feeling more confident.
Thanks for the advice. Good to know there's somewhere else to turn when O2 stick me in a queue.
