I wrote before about this. I got a Net10 Samsung S390G phone online. I didn't realize it was a Net10 phone until I received it but I really prefer it under my Tracfone account. As soon as I put the Net10 SIM back in the phone was registered to Net10. There are a lot of unlock instructions on the web for that phone. Can I trust any of them and can I even unlock a phone that has already been registered? Thanks.
