What do you do if a guy calls, but doesn't leave a message, but then texts 2 hours later?

I have been hanging out with this guy for about a month and a half. We hung out three out of the 4 nights he was around last week. He went out on his boat on Friday to a port north of here and has been there all weekend. He called me tonight, but I missed the call, and he didn't leave a message. He texted me 2 hrs later saying that he had tried calling, and that he'd be up north for a few more days. I don't know whether I should call him back or simply reply by text. I really would like to call him, but I don't want to come across as too available etc.
