AT&T and Verizon are both offering free long distance calls and texts to Japan for the next few weeks. AT&T is offering free calls and texts from the U.S. until March 31, while Verizon is doing the same through April 10.
Chances are if you’re making calls and texts to Japan, then you know somebody there. Google has set up a Crisis Response page that includes a free “people tracker” tool for locating missing loved ones. I hope you do not need to use it, but it’s there if needed.
