If I blocked someone on iPhone?

Ok, so the situation is I told off this guy for being an ***hole, and him and his little friend keep texting me stuff I don't wanna hear. I put my phone on airplane mode so I wouldn't receive any texts for a while, and then while it was on airplane mode, I blocked them. My question is, if I blocked them while the phone was on airplane mode, will I receive their messages when I go off airplane mode? I don't want to even see the texts, honestly. So is it ok for me to turn off airplane?

Blocked is Blocked. Take airplane off, and move on. Best luck.

Thank you!
