The number of details

Now I am used to moving, I have averaged approximately 1 move per year since college. It gets tiring, but manageable. The latest addition today though surprised me. AT&T needs to send us a new SIM card, one that is optimized for our new location (ie we cannot make or receive calls most of the time). Now, if this is the case, would that mean i could not travel to the west coast (or vice-versa) and get reception? "Can you hear me now?" At least this has been an easier problem to fix...If only my list of things to do would decrease though!
