The first call you might receive is at about the third week into training. Might receive is the key. Phone calls are never given although one at about three weeks is usual. Always look forward to a call, but never expect one. Keep your phone close all the time, and answer every call. A call from your recruit may come from Pay Phone, Gov't Phone, area code 847, or many other area codes.
My son left March 12. I have been an emotional roller coaster since and just wanted to say thank you for sharing it is really relatable and more helpful than I ever imagined!!!
My son also left for GL boot camp on March 12. I got the call that night that he arrived safely. It was like 30 seconds long and sounded so "mechanical" I received another call from him on Monday, he informed me that he had a division change and that his graduation date was May 10. I'm yet to receive the formal letter with his address though. I got it from his recruiter today since I was not able to write down what he told me.
