I have a long commute in and out of a large city. Since I spend so much time on the road, I always try to get the details of Amber Alert notifications to be on the lookout for vehicles used in abductions. I guess I can't do that anymore since Twitter requires an account to see Amber Alerts. Hopefully my state finds another platform to post them.
Phone services are required to put out the message though, just like you're able to dial 911 from a phone even if you don't have service (if you're in a covered area).
