Of course I wish this was happening for a less terrible reason, but both AT&T and Verizon are offering free calls/texts to Japan right now; AT&T, through the end of March, and Verizon through April 10th. [Edited to add: T-Mobile has joined the trend, as well. Hooray!]
Don’t forget that you can easily donate $10 to the Red Cross via texting REDCROSS to 90999, too (it’ll be added to your phone bill).
Awesome…wonder if T-Mobile will follow? My brother is in Japan, and so far, unaffected, fingers crossed it stays that way.
