Forwarding a text message to an email from an iPhone is similarly easy, although the same caveats concerning iMessage apply when forwarding a message as when sending a new one, so you may have to bypass that if you find the email address turns blue and you want to force it to go out via email instead. Also be sure that MMS is enabled in Settings > Messages, as described above. I am not sure it the action you mentioned is supported. We can leave this post open in case anyone else has a suggestion. A WARNING before we proceed. When sending an email to be forwarded as an SMS do consider that there is up to 160 character limit on SMS and if your body includes more characters it will be separated into several SMS. The cost for sending SMS is per each SMS or per part so if you send a big email it can multiply the cost depending on how many parts where used. Make sure you clear all the text from your emails when forwarding or replying so that only the main text you want to actually send is sent.
