    Never heard of a r-uim card. CDMA technology is used by activating the esn on the device. You will need to contact your carrier.

    It may not be unlocked. follow the following instructions and reply with what you see after the last step with the SIM card inside;

    1. Go to settings menu and then Options
    2. Select Advanced options and then SIM card
    3. Type MEPD using your Blackberry keyboard (NOTE: You will not see any text appear on the screen while typing MEPD)
