We spoke to a woman in Watertown, Massachusetts, this morning who said she did not get the 'reverse 911' or 'robo-call' from the city warning people to 'shelter in place' while police search for a 19-year-old suspect in the Boston Marathon bombings. She didn't get the call because, like many people, she does not have a landline, and her cell phone has an out-of-state phone area code.
So, if you don't have a landline, how can you make sure you get vital information in an emergency?
HLN's Jennifer Westhoven reports that the answer depends on where you live and what type of phone you use.
