Can I ship things to my boyfriend in boot camp?

Right now my bf has a Stylo 4. My step dad is selling me a brand new IPhone XS & I would like to give it to my bf so that when he can finally use his phone, we can FaceTime. By then, I’ll be in college and he’ll still be in Georgia. I’m gonna get the phone this week & I don’t know if I should wait until August when I go see him or ship it to him once it’s in my hands. I don’t even know if i’m allowed to which is why I’m asking. The sooner the better imo, but idk how it works with them.
