Extended information, what does this function do?
Extended information will retrieve additional information about the requested IMEI number, such as, registered carrier, network status and if it was originally SIM-Locked or not.

What is Network status?
Network status shows weither the specific IMEI is rejected by the registered carriers network or not. Included in extended information.

I have a brand new phone which I need to activate, I do not know which carrier it is from?
Check "Extended information" and place your IMEI in queue, check back after a few hours.

I see only "In queue" and "Queued?" What is this???
As extended information is stored in a secondary database server which is only reachable a few times per day, the processing may take up to 8 hours, but, if you have luck, your information can be retrieved after an hour.
