A Verizon phone, and you have to check the ESN or IMEI at Straight Talk Compatibility Test to see if you can use that particular phone with Straight Talk. (It's up to Verizon, not Straight Talk.)

If it's a generic CDMA phone or an unlocked Sprint phone, it won't pass the test - the number has to be in Verizon's database for starters (and only their branded phones are, except for the Straight Talk or Net 10 branded phones for use on Verizon's towers).
