Interesting coincidence. I just ordered a new Tracfone for 50 bucks. I had assumed the unlock policy was 1 year. The same phone, unlocked, was much more expensive. Strategically, I figured that after being a Tracfone customer for well over a decade, I probably wouldn't get around to switching for yet another year, so I'm OK.
Well, I don't know if people ever look at old threads, but I had an inspiration, and decided to unlock my old phone before switching to the new one. Tracfone made it utterly painless. Now I have an unlocked phone should I ever travel to a faraway place and need to get a local SIM card.
