Pictures and notes

So my boyfriend (19) is leaving for the army soon, and my family (I'm 17) has decided that we're goin to put him on our phone plan. I was thinking about before he leaves for basic have him pick one out and then while he's in basic fill it with pictures and note ( not like over doing it or anything) and then giving him it when he goes to AIT. Good plan? Or should I just leave his new phone blank?
