Should I send him a message for him to see when he gets back?

I’ve gone out with this guy for a while and it’s been going well. He went off for a week long training for the marines and can’t have his phone and texted me before he left that he misses me and wants to see me when he gets back. I don’t know if I should send him a message close to when he gets back so he can see it when he does get his phone again? And if so what to say?
