First of all a very warm welcome to the eForum, it is great to see new users!
I will gladly help with this. As the PIN is unique to yourself I will need to look at your account in more detail. I have sent you an email to complete and reply to, this way we can progress and resolve your query.
you DO NOT need to release PIN`s anymore, it automatically transfers when a new BIS/BES enabled simcard is placed into the device. this has been the case for over a year now since BIS3.0 was rolled out.
