No SIM Card?

• Does this situation sound familiar to you?
• You have been using your iPhone without any
  concerns, and then all of a sudden you are
  presented with a message that says "No SIM Card
  Installed," "Invalid SIM," or "Insert SIM.
• This is not an issue unique to the newest iPhone.
  There have been complaints about the same message
  on the original iPhone. And the problem isn't
  even unique to the iPhone people are making the
  same complaints about other phones that use SIM
  cards.

Why Does IPhone Not Accept the SIM Card?

• It is hard to pinpoint the exact reason why
  iPhones that use a SIM card display error
  messages at random times. Sometimes it is a
  simple glitch that cannot be fully explained, and
  at other times it is due to an issue with the
  iPhone being too hot or the presence of dust on
  the SIM card itself. Worst case scenario, the SIM
  card could be defective, and that would require
  you to get a new SIM card to install on the
  phone.
• You are not alone, and there are a few things you
  can do yourself, for free, to diagnose the cause
  and solve it.

OVERVIEW

• Apple also advises that you should ensure that
  the following areas have been considered
• Check to see if there is an update for your
  carrier by going to Settings gt General gt
  About. If an update is available, a prompt will
  appear.
• Restore the iPhone by connecting it to a computer
  and re-syncing with iTunes.
• There are some phones that do not use a SIM card
  at all. Instead of using a SIM, these phones have
  an electronic serial number that is tracked by
  the phone carrier, so there is no need to store
  the information on a SIM card as the carrier has
  a list of all the phones in use in their network.
