I tried to transfer my Verizon Samsung S4 to TracFone. They said it should work but after multiple attempts they could not manage the transfer. They claimed it would be at least 24 hours before they could figure out the problem. I asked if I could put my Verizon SIM card back in so I could use my phone. They said "Yes" but then they couldn't continue with my transfer so I told them "No thanks". I wish I'd looked up reviews for these buggers before I spent $10 for their SIM card and $20 on the airtime card. After I was on the phone for over an hour my wife googled TracFone and found they are one star only because you can't give 0 stars.
