 @54ea3b55 @67fa73ee It’s treated differently from an SMS - It’s a broadcast from each base station to any handset rather than addressed to each subscriber. So if you’re in range of a base station during the period where it’s broadcast, you get it (once, and then your phone ignores duplicates of the same message). It was broadcast for 20 minutes during today’s test. so if your phone was off from about 2:20-2:40 eastern, you wouldn’t ever see it.
