Today when a customer purchases a cellular phone, they must call into a service center and follow a series of steps to activate the phone so they can use it. Additionally, if the customer buys a replacement phone, they must repeat this process and there is the added problem of migrating personal information and preferences. Since the process of setting up the phone and enabling the account can be a cumbersome, what is needed is a method and system to store cellular phone account and personal information/preferences in a persistent and transportable manner. A small wireless device can be used to store the SIM (Subscriber Indentity Model) data for the cell phone account. This small device could also store personalized information such as phone book entries, quick dial settings (number and voice if supported), ring tones, volume preferences, games, internet settings including bookmarks, IM data, and other data/prefeferences. This data could be transmitted to a compatible cellular phone via a learn/synch mode. Thus facilitating easy cell phone activation and even enabling users to temporarily program a borrowed phone using their own account instead of someone else's. The data would be encrypted on the SIM-FOB and the sync operation would be protected using PKI authentication, which would only initiated after entering a password. With this method, the key fob could be sold seperately from the phone being used.
