Last October, T-Mobile made an astonishing announcement: from now on, when you travel internationally with a T-Mobile phone, you get free unlimited text messages and Internet use. Phone calls to any country are 20 cents a minute.
T-Mobile’s plan changes everything. It ends the age of putting your phone in airplane mode overseas, terrified by tales of $6,000 overage charges. I figured my readers would be jubilant. But a surprising number had a very different reaction. “Why should I believe them?” they wrote. “Cell carriers have lied to us for years.”
