Hub and Spoke package delivery systems

I ordered a new cell phone plan and AT&T is shipping me a 3G SIM for the GSM phone.  My little SIM card started it's journey pert near my house.  It's taking the scenic route to get there.  Can you guess who the carrier is?  You would think some "sort" of exception would be made on routes like this, but I guess a system is a system, right?
