MMS is an extension of SMS, so if you are charged per message for texts, then yes, you would get charged for it.
If you are trying to send an iMessage, that would need to go to a reciepient with an Apple device and iMessage address registered on thier AppleID. Otehrwise is will be send and SMS or MMS. iMessages will impact your data plan.

So would I have to switch iMessage off when sending sms to a non iPhone user?

No you shouldn't have to. There is a setting called "Ssend as SMS" that should be turned ON however. If the message is going to a non iMessage device, it will send it as SMS (even if iMessage is turned on).
