UH-OH, did I do a bad thing?

I just started getting spam texts,well this is the third one, and I thought i'd mess with them and tried to reply with"just your # to FCC". I got a messge that said it failed and saved it to outlook. Is that thing now embedded on my SIM card and screw up my phone(or worse,use my no. to call others)? I went ahead and shut it off. TIA!
