Contact your phone carrier to see how to do this.

  • Lost iPhone containing important phone number what can I do? I lost an iPhone a few weeks ago that contained a very important phone number of mine. Sadly I didn't back up my device and don't use iCloud. Would there be any way of retrieving that phone number? Or am I screwed?
  • Just switched my number to a new iphone, but my old phone still works? I just went and started an individual plan and got a new iphone 5, and they carried over my number from the virgin mobile prepaid i had before. My new iphone can make calls and send and receive texts… But so can my old phone. And when i called my cell number using my house phone, my old phone rang, but my new iphone didn't. Do i have to like cancel service or something? I'm confused about what to do, the guys at apple didn't mention anything about it.
