So I'm on my 2nd Tour with Sprint and as soon as I called the International Services I had asked if I could get my phone unlocked because I was traveling over seas, so the lady had told me to do the
Options-Advanced Options-Sim Card- Type: MEPD and if it said "Disabled" then my phone was unlocked and if it said another word, I think it started with an "A" then my phone was locked.
So my Sim Card says : Security Disabled
ID: 19-Digit Number
Personalization:
Sim: Disabled
Network: Disabled
Network Subset: Disabled
Service Provider: Disabled
Corporate: Disabled
I haven't tried using a different carriers' SIM Card with my Tour but is my phone Unlocked?
