Editing Universal integrated circuit card (section)

== Usage ==

Since the card slot is standardized, a subscriber can easily move their wireless account and phone number from one handset to another. This will also transfer their phone book and text messages. Similarly, usually a subscriber can change carriers by inserting a new carrier's UICC card into their existing handset. However, it is not always possible because some carriers (e.g., in U.S.) ''[[SIM lock|SIM-lock]]'' the phones that they sell, preventing rival carriers' cards from being used.

The use and content of the card can be protected by use of [[Personal identification number|PIN]] codes. One code, PIN1, can be defined to control normal use of the phone. Another code, PIN2, can be set, to allow the use of special functions (like [[Fixed Dialing Number|limiting outbound telephone calls to a list of numbers]]). [[Personal unblocking code|PUK1]] and PUK2 is used to reset PIN1 and PIN2 respectively.

The integration of the ETSI framework and the Application management framework of [[GlobalPlatform]] is standardized in the UICC configuration.<ref>{{cite web|last=Ericsson|first=Daniel|title=The OTA Platform in the World of LTE|url=http://www.carabinerpr.com/pdf/WP_OTA_and_LTE_Jan_11.pdf|website=carabinerpr.com|publisher=Giesecke & Devrient|access-date=5 January 2013|date=January 2011}}</ref>
