Hi, when a phone displays an insert sim message, it means that either the Sim card or the Sim tray where the sim card is inserted in the phone.

First, You can use the sim card on another phone to be sure that the sim card is still working properly. If the sim works with another phone, that means the sim tray where the sim card is being insert into the phone is bad and will need to be replaced.

You `can contact a skill personnel for help.

Have a nice day.

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.

go to phone book then managment then copy all to then sim card.

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.
