T-Mobile's latest Un-carrier offering is going straight for Verizon's jugular. It's called the "Never Settle Trial," and as you might have guessed, it specifically mocks Big Red's #NeverSettle ad campaign. The trial, exclusively available to Verizon subscribers, will give you free access to a T-Mobile phone with an Un-carrier plan for two full weeks. You can even port your Verizon number without cutting your old line. If you decide to sign up for a Big Magenta Simple Choice plan by the end of the 14-day period, Legere and co. promise to shoulder any Early Termination Fee you incur worth up to $650. Actually, the company swears to pay for any service costs incurred due to the trial, even if you decide to stick with Verizon.
