If you need to reach someone in Chile this week, try calling on a Verizon or T-Mobile phone. Both carriers have announced that they’re temporarily waiving charges on calls. Verizon says that all calls from the U.S. to Chile will be free until March 6th. I couldn’t find a similar press release from T-Mobile, so you might want to call first to confirm. Just remember that only these two carriers are offering free calls, and they’re only free if you call from the U.S.; you don’t want to end up with an unpleasant surprise like those U.S. soldiers in Haiti last month.
