I bought my BB from ebay a couple of days ago, it was listed as new and unlocked. I verified that it is unlocked from the SIM card section through Options->Advanced Options-->Sim Card. (All options are disabled) from: BlackberryForumsFAQ
I do not have a contract since I will be traveling soon and wanted to buy the SIM card with BB plan at my destination. As of now I only have the phone.
My problem is that I tried creating a BIS account to verify if the phone was ready to be used once I got to my destination. Once I tried creating the account through the AT&T site I received a message that "This BB device is registered with another carrier".
I thought it might be one of these two problems: 1) I do not have a BB plan yet or 2) my PIN has not been released.
I emailed the seller asking for the carrier to which this phone was registered and if he can ask that carrier to release the PIN but I haven't receive an answer yet.
Any suggestions are greatly appreciated!! Thanks!!
You will need to contact the seller and have them get the PIN released from the old network or call the old provider yourself and sweet talk them into it.
