MMS are not the same as "iMessages".
If you are trying to send a message to someone without an iPhone, iPad, or Mac, but to a regular mobile phone, it will have to use your phone provider MMS service - and, probably, pay its fee. This will of course need to be rerouted via your iPhone, since your Mac does not have mobile service. I don't use MMS, but it stands to reason that this is something that would need to be enabled on your iPhone.
