    Tmobile prepaid has locked SIM card?

    Guys

    I tried using the SIM card on my tmobile prepaid phone today on a friend's blackberry and it popped this error:
    Your current sim card requires an unlock code. Would you like to unlock it

    1) I didn't know SIM cards could be locked as well; knew about phones. What exactly does a locked SIM card prevent? I guess it is tied only to a single phone?

    2) If i call tmobile, would they unlock the sim card for me or provide me the code?

    3) Can i unlock the sim card directly from the prepaid phone that I got? Don't see any options on this simple nokia phone

    Thanks guys

    Some SIM cards can be locked, and you need a PIN to unlock them. (PUK code)

    Was your friend's BlackBerry on T-Mobile? If it wasn't you need an unlock code so you can use it with T-Mobile.

    The other thing is does the BlackBerry have a security code which is needed to be entered for another SIM?

    Is there a PIN code on the SIM?

    A SIM PIN is different than a PUK. A PUK (Phone Unlock Key) is only needed if you attempt to enter a SIM PIN and incorrectly enter a PIN code three times. PUK unlocks the SIM so you can enter a new code.

    Tracfone/Net10 has "locked" SIM so you can't use it with ANY phone even it's unlocked.
