First Claim
Patent Images
1. A method for initializing a subscriber identity module (SIM) card, the method comprising:
- sending a request to read a file from the SIM card;
receiving a SIM version identifier for the file from the SIM card;
determining whether the SIM version identifier matches a cached version identifier in a cache; and
accessing the file from the cache when the SIM version identifier matches the cached version identifier.

Abstract
Methods and apparatus for initializing a SIM card may include sending a request to read a file from the SIM card. In addition, the methods and apparatus may include receiving a SIM version identifier for the file from the SIM card and determining whether the SIM version identifier matches a cached version identified in a cache. When the SIM version identifier matches the cached version identifier, the methods and apparatus may include accessing the file from the cache.
