It comes up with Insert SIM Emergency? What is SIM?


A SIM card or Subscriber Identity Module is a portable memory chip used in some models of cellular telephones. The SIM card makes it easy to switch to a new phone by simply sliding the SIM out of the old phone and into the new one. The SIM holds personal identity information, cell phone number, phone book, text messages and other data. It can be thought of as a mini hard disk that automatically activates the phone into which it is inserted.

A SIM card can come in very handy. For example, let's say your phone runs out of battery power at a friend's house. Assuming you both have SIM-based phones, you can remove the SIM card from your phone and slide it into your friend's phone to make your call. Your carrier processes the call as if it were made from your phone, so it won't count against your friend's minutes.

If you upgrade your phone there's no hassle involved. The SIM card is all you need. Just slide it into the new phone and you're good to go. You can even keep multiple phones for different purposes. An inexpensive phone in the glove compartment, for example, for emergency use, one phone for work and another for home. Just slide your SIM card into whatever phone you wish to use.

High-end cell phones can be very attractive and somewhat pricey. If you invest in an expensive phone you might want to keep it awhile. Using a SIM card, it is even possible to switch carriers and continue to use the same phone. The new carrier will simply issue you their own SIM card. The phone must be unlocked, however, and operate on the new carrier's frequency or band.


When it's not inserted properly, it displays insert .You will need to insert the sim card properly so that the message won't come up again..

I changed sim card, now they both display ''Insert SIM''


try taking out both cards and popping the battery on the phone.

Wait a few minutes and then turn the phone on with no card in it.

Turn it back off when it says no card found and insert the newer card and power it back up.

It seemed to keep a memory of the blank card.

Sim card on Samsung sync


You have most likely already checked this, but just in case.....make sure the sim card is full inserted, and inserted in the correct position. (There should be a diagram showing which way to insert the card.

Hope this helps.
