If the big cell phone companies were like the British Empire, Straight Talk was like the American colonies, rebelling against a system that seemed to treat its customers like cash registers. Straight Talk believed it was possible to offer good, reliable service and fast speeds without charging an arm and a leg and without locking their customers into interminable contracts. And guess what? They were right. Now they're the biggest no contract provider in America, offering customers 5 GB of high-speed data, plus unlimited texting and calling — all for just $45 and no contract.
