Hello. My son is currently in boot camp. We received a letter from Cape May with general information and company assignment/mailing address about a week after our son reported. The initial letter is very thorough including a letter from command and the chaplain. Look over the purple Helmsman handbook which your son received from his recruiter before he leaves. The information detailing each training week offers insight into what will take place and a timeline if when. I would try to resolve the call dropping dilemma with my cell phone provider to save yourself a lot of anxiety over missed calls. Pray all goes well and this is helpful.
