Replace or merge contacts on your wireless service provider's contact backup server
In order to perform this task, you will need to sign up for your wireless service provider's contact backup service and you must have backed up your SIM card phone book to your wireless service provider's contact backup server. When you insert a new SIM card in your BlackBerry® smartphone, you can choose to replace or merge that SIM card's phone book with the contacts that you have backed up on your wireless service provider's contact backup server.
