Apple warned over built-in Sim cards

Some of Europe's leading mobile operators are warning that they could take punitive action against Apple if it introduces a technological innovation on its iPhone. The operators are privately saying they could refuse to subsidize the iPhone if Apple inserts an embedded subscriber identity module, or Sim card. The operators are accusing Apple of trying to gain control of their relationship with their mobile customers with the new Sim. The technology could allow customers to buy the iPhone and sign up for service on Apple's website and start using it immediately. Closer to the operators' hearts, it could allow customers to switch more easily from one to another or insist on shorter-term contracts. It could even set the stage for Apple to resell connection service on its own, although the company has not indicated such plans.
