A3M has your back if you should find yourself traveling in an area at risk of a tsunami. This clever group has its fingers in research stations all around the globe, constantly checking reports of underwater seismic activity. If a seismic event occurs, all subscribers in the affected area will receive 3 SMS flash messages in a row warning of impending doom. Subscription pricing comes in a few different flavors: one year subscription for $40, one month for $13, and a bulk package with 5 to 1000 users. The idea behind this is sound, and if it saves lives, we are all for it -- but we can't help worry that if your subscription expires or you are out of a coverage area, you could be up the creek.
