While on a call with my carrier, changing to newer voice and data plans to save a bit of cash, this error popped up on my iPhone: “UICC Update failed 2” with accept or decline options at the bottom. After reading about the Universal Integrated Circuit Card at WikiPedia, it became apparent this error must have been related to changing my service options. The error happened twice, once for each edit the customer service representative made.
