问题补充说明：请问句中的"unlocked" phones是什么意思，是滑盖手机？还是没有密码的手机？还是。。。谢谢 Stymied by U.S. wireless carriers, Nokia has begun selling "unlocked" phones, which are devices that can work on any wireless network, directly to consumers. All users need to do is remove the SIM card from their old phone, insert it into a new one, and -- voila -- start dialing.
unlocked是没上锁的意思吧
